+================================================================================
+Simple DirectMedia Layer for Android
+================================================================================
+
+Requirements:
+
+Android SDK (version 10 or later)
+http://developer.android.com/sdk/index.html
+
+Android NDK r7 or later
+http://developer.android.com/sdk/ndk/index.html
+
+Minimum API level supported by SDL: 10 (Android 2.3.3)
+
+================================================================================
+ How the port works
+================================================================================
+
+- Android applications are Java-based, optionally with parts written in C
+- As SDL apps are C-based, we use a small Java shim that uses JNI to talk to
+the SDL library
+- This means that your application C code must be placed inside an Android
+Java project, along with some C support code that communicates with Java
+- This eventually produces a standard Android .apk package
+
+The Android Java code implements an "Activity" and can be found in:
+android-project/src/org/libsdl/app/SDLActivity.java
+
+The Java code loads your game code, the SDL shared library, and
+dispatches to native functions implemented in the SDL library:
+src/SDL_android.c
+
+Your project must include some glue code that starts your main() routine:
+src/main/android/SDL_android_main.c
+
+
+================================================================================
+ Building an app
+================================================================================
+
+Instructions:
+1. Copy the android-project directory wherever you want to keep your projects
+ and rename it to the name of your project.
+2. Move or symlink this SDL directory into the <project>/jni directory
+3. Edit <project>/jni/src/Android.mk to include your source files
+4. Run 'ndk-build' (a script provided by the NDK). This compiles the C source
+
+If you want to use the Eclipse IDE, skip to the Eclipse section below.
+
+5. Create <project>/local.properties and use that to point to the Android SDK directory, by writing a line with the following form:
+sdk.dir=PATH_TO_ANDROID_SDK
+6. Run 'ant debug' in android/project. This compiles the .java and eventually
+ creates a .apk with the native code embedded
+7. 'ant debug install' will push the apk to the device or emulator (if connected)
+
+Here's an explanation of the files in the Android project, so you can customize them:
+
+android-project/
+ AndroidManifest.xml - package manifest. Among others, it contains the class name
+ of the main Activity and the package name of the application.
+ build.properties - empty
+ build.xml - build description file, used by ant. The actual application name
+ is specified here.
+ default.properties - holds the target ABI for the application, android-10 and up
+ project.properties - holds the target ABI for the application, android-10 and up
+ local.properties - holds the SDK path, you should change this to the path to your SDK
+ jni/ - directory holding native code
+ jni/Android.mk - Android makefile that can call recursively the Android.mk files
+ in all subdirectories
+ jni/SDL/ - (symlink to) directory holding the SDL library files
+ jni/SDL/Android.mk - Android makefile for creating the SDL shared library
+ jni/src/ - directory holding your C/C++ source
+ jni/src/Android.mk - Android makefile that you should customize to include your
+ source code and any library references
+ res/ - directory holding resources for your application
+ res/drawable-* - directories holding icons for different phone hardware. Could be
+ one dir called "drawable".
+ res/layout/main.xml - Usually contains a file main.xml, which declares the screen layout.
+ We don't need it because we use the SDL video output.
+ res/values/strings.xml - strings used in your application, including the application name
+ shown on the phone.
+ src/org/libsdl/app/SDLActivity.java - the Java class handling the initialization and binding
+ to SDL. Be very careful changing this, as the SDL library relies
+ on this implementation.
+
+
+================================================================================
+ Customizing your application name
+================================================================================
+
+To customize your application name, edit AndroidManifest.xml and replace
+"org.libsdl.app" with an identifier for your product package.
+
+Then create a Java class extending SDLActivity and place it in a directory
+under src matching your package, e.g.
+ src/com/gamemaker/game/MyGame.java
+
+Here's an example of a minimal class file:
+--- MyGame.java --------------------------
+package com.gamemaker.game;
+
+import org.libsdl.app.SDLActivity;
+
+/*
+ * A sample wrapper class that just calls SDLActivity
+ */
+
+public class MyGame extends SDLActivity { }
+
+------------------------------------------
+
+Then replace "SDLActivity" in AndroidManifest.xml with the name of your
+class, .e.g. "MyGame"
+
+================================================================================
+ Customizing your application icon
+================================================================================
+
+Conceptually changing your icon is just replacing the "ic_launcher.png" files in
+the drawable directories under the res directory. There are four directories for
+different screen sizes. These can be replaced with one dir called "drawable",
+containing an icon file "ic_launcher.png" with dimensions 48x48 or 72x72.
+
+You may need to change the name of your icon in AndroidManifest.xml to match
+this icon filename.
+
+================================================================================
+ Loading assets
+================================================================================
+
+Any files you put in the "assets" directory of your android-project directory
+will get bundled into the application package and you can load them using the
+standard functions in SDL_rwops.h.
+
+There are also a few Android specific functions that allow you to get other
+useful paths for saving and loading data:
+SDL_AndroidGetInternalStoragePath()
+SDL_AndroidGetExternalStorageState()
+SDL_AndroidGetExternalStoragePath()
+
+See SDL_system.h for more details on these functions.
+
+The asset packaging system will, by default, compress certain file extensions.
+SDL includes two asset file access mechanisms, the preferred one is the so
+called "File Descriptor" method, which is faster and doesn't involve the Dalvik
+GC, but given this method does not work on compressed assets, there is also the
+"Input Stream" method, which is automatically used as a fall back by SDL. You
+may want to keep this fact in mind when building your APK, specially when large
+files are involved.
+For more information on which extensions get compressed by default and how to
+disable this behaviour, see for example:
+
+http://ponystyle.com/blog/2010/03/26/dealing-with-asset-compression-in-android-apps/
+
+================================================================================
+ Pause / Resume behaviour
+================================================================================
+
+If SDL is compiled with SDL_ANDROID_BLOCK_ON_PAUSE defined (the default),
+the event loop will block itself when the app is paused (ie, when the user
+returns to the main Android dashboard). Blocking is better in terms of battery
+use, and it allows your app to spring back to life instantaneously after resume
+(versus polling for a resume message).
+
+Upon resume, SDL will attempt to restore the GL context automatically.
+In modern devices (Android 3.0 and up) this will most likely succeed and your
+app can continue to operate as it was.
+
+However, there's a chance (on older hardware, or on systems under heavy load),
+where the GL context can not be restored. In that case you have to listen for
+a specific message, (which is not yet implemented!) and restore your textures
+manually or quit the app (which is actually the kind of behaviour you'll see
+under iOS, if the OS can not restore your GL context it will just kill your app)
+
+================================================================================
+ Threads and the Java VM
+================================================================================
+
+For a quick tour on how Linux native threads interoperate with the Java VM, take
+a look here: http://developer.android.com/guide/practices/jni.html
+If you want to use threads in your SDL app, it's strongly recommended that you
+do so by creating them using SDL functions. This way, the required attach/detach
+handling is managed by SDL automagically. If you have threads created by other
+means and they make calls to SDL functions, make sure that you call
+Android_JNI_SetupThread before doing anything else otherwise SDL will attach
+your thread automatically anyway (when you make an SDL call), but it'll never
+detach it.
+
+================================================================================
+ Using STL
+================================================================================
+
+You can use STL in your project by creating an Application.mk file in the jni
+folder and adding the following line:
+APP_STL := stlport_static
+
+For more information check out CPLUSPLUS-SUPPORT.html in the NDK documentation.
+
+================================================================================
+ Additional documentation
+================================================================================
+
+The documentation in the NDK docs directory is very helpful in understanding the
+build process and how to work with native code on the Android platform.
+
+The best place to start is with docs/OVERVIEW.TXT
+
+
+================================================================================
+ Using Eclipse
+================================================================================
+
+First make sure that you've installed Eclipse and the Android extensions as described here:
+ http://developer.android.com/sdk/eclipse-adt.html
+
+Once you've copied the SDL android project and customized it, you can create an Eclipse project from it:
+ * File -> New -> Other
+ * Select the Android -> Android Project wizard and click Next
+ * Enter the name you'd like your project to have
+ * Select "Create project from existing source" and browse for your project directory
+ * Make sure the Build Target is set to Android 2.0
+ * Click Finish
+
+
+================================================================================
+ Using the emulator
+================================================================================
+
+There are some good tips and tricks for getting the most out of the
+emulator here: http://developer.android.com/tools/devices/emulator.html
+
+Especially useful is the info on setting up OpenGL ES 2.0 emulation.
+
+Notice that this software emulator is incredibly slow and needs a lot of disk space.
+Using a real device works better.
+
+================================================================================
+ Troubleshooting
+================================================================================
+
+You can create and run an emulator from the Eclipse IDE:
+ * Window -> Android SDK and AVD Manager
+
+You can see if adb can see any devices with the following command:
+ adb devices
+
+You can see the output of log messages on the default device with:
+ adb logcat
+
+You can push files to the device with:
+ adb push local_file remote_path_and_file
+
+You can push files to the SD Card at /sdcard, for example:
+ adb push moose.dat /sdcard/moose.dat
+
+You can see the files on the SD card with a shell command:
+ adb shell ls /sdcard/
+
+You can start a command shell on the default device with:
+ adb shell
+
+You can remove the library files of your project (and not the SDL lib files) with:
+ ndk-build clean
+
+You can do a build with the following command:
+ ndk-build
+
+You can see the complete command line that ndk-build is using by passing V=1 on the command line:
+ ndk-build V=1
+
+If your application crashes in native code, you can use addr2line to convert the
+addresses in the stack trace to lines in your code.
+
+For example, if your crash looks like this:
+I/DEBUG ( 31): signal 11 (SIGSEGV), code 2 (SEGV_ACCERR), fault addr 400085d0
+I/DEBUG ( 31): r0 00000000 r1 00001000 r2 00000003 r3 400085d4
+I/DEBUG ( 31): r4 400085d0 r5 40008000 r6 afd41504 r7 436c6a7c
+I/DEBUG ( 31): r8 436c6b30 r9 435c6fb0 10 435c6f9c fp 4168d82c
+I/DEBUG ( 31): ip 8346aff0 sp 436c6a60 lr afd1c8ff pc afd1c902 cpsr 60000030
+I/DEBUG ( 31): #00 pc 0001c902 /system/lib/libc.so
+I/DEBUG ( 31): #01 pc 0001ccf6 /system/lib/libc.so
+I/DEBUG ( 31): #02 pc 000014bc /data/data/org.libsdl.app/lib/libmain.so
+I/DEBUG ( 31): #03 pc 00001506 /data/data/org.libsdl.app/lib/libmain.so
+
+You can see that there's a crash in the C library being called from the main code.
+I run addr2line with the debug version of my code:
+ arm-eabi-addr2line -C -f -e obj/local/armeabi/libmain.so
+and then paste in the number after "pc" in the call stack, from the line that I care about:
+000014bc
+
+I get output from addr2line showing that it's in the quit function, in testspriteminimal.c, on line 23.
+
+You can add logging to your code to help show what's happening:
+
+#include <android/log.h>
+
+ __android_log_print(ANDROID_LOG_INFO, "foo", "Something happened! x = %d", x);
+
+If you need to build without optimization turned on, you can create a file called
+"Application.mk" in the jni directory, with the following line in it:
+APP_OPTIM := debug
+
+
+================================================================================
+ Memory debugging
+================================================================================
+
+The best (and slowest) way to debug memory issues on Android is valgrind.
+Valgrind has support for Android out of the box, just grab code using:
+ svn co svn://svn.valgrind.org/valgrind/trunk valgrind
+... and follow the instructions in the file README.android to build it.
+
+One thing I needed to do on Mac OS X was change the path to the toolchain,
+and add ranlib to the environment variables:
+export RANLIB=$NDKROOT/toolchains/arm-linux-androideabi-4.4.3/prebuilt/darwin-x86/bin/arm-linux-androideabi-ranlib
+
+Once valgrind is built, you can create a wrapper script to launch your
+application with it, changing org.libsdl.app to your package identifier:
+--- start_valgrind_app -------------------
+#!/system/bin/sh
+export TMPDIR=/data/data/org.libsdl.app
+exec /data/local/Inst/bin/valgrind --log-file=/sdcard/valgrind.log --error-limit=no $*
+------------------------------------------
+
+Then push it to the device:
+ adb push start_valgrind_app /data/local
+
+and make it executable:
+ adb shell chmod 755 /data/local/start_valgrind_app
+
+and tell Android to use the script to launch your application:
+ adb shell setprop wrap.org.libsdl.app "logwrapper /data/local/start_valgrind_app"
+
+If the setprop command says "could not set property", it's likely that
+your package name is too long and you should make it shorter by changing
+AndroidManifest.xml and the path to your class file in android-project/src
+
+You can then launch your application normally and waaaaaaaiiittt for it.
+You can monitor the startup process with the logcat command above, and
+when it's done (or even while it's running) you can grab the valgrind
+output file:
+ adb pull /sdcard/valgrind.log
+
+When you're done instrumenting with valgrind, you can disable the wrapper:
+ adb shell setprop wrap.org.libsdl.app ""
+
+================================================================================
+ Why is API level 10 the minimum required?
+================================================================================
+
+API level 10 is required because SDL requires some functionality for running not
+available on older devices and some for building which is not in older NDK/SDKs.
+
+Support for native OpenGL ES and ES2 applications was introduced in the NDK for
+API level 4 and 8. EGL was made a stable API in the NDK for API level 9, which
+has since then been obsoleted, with the recommendation to developers to bump the
+required API level to 10.
+As of this writing, according to http://developer.android.com/about/dashboards/index.html
+about 90% of the Android devices accessing Google Play support API level 10 or
+higher (March 2013).
+
+================================================================================
+ A note regarding the use of the "dirty rectangles" rendering technique
+================================================================================
+
+If your app uses a variation of the "dirty rectangles" rendering technique,
+where you only update a portion of the screen on each frame, you may notice a
+variety of visual glitches on Android, that are not present on other platforms.
+This is caused by SDL's use of EGL as the support system to handle OpenGL ES/ES2
+contexts, in particular the use of the eglSwapBuffers function. As stated in the
+documentation for the function "The contents of ancillary buffers are always
+undefined after calling eglSwapBuffers".
+Setting the EGL_SWAP_BEHAVIOR attribute of the surface to EGL_BUFFER_PRESERVED
+is not possible for SDL as it requires EGL 1.4, available only on the API level
+17+, so the only workaround available on this platform is to redraw the entire
+screen each frame.
+
+Reference: http://www.khronos.org/registry/egl/specs/EGLTechNote0001.html

+CMake build system for SDL (www.cmake.org)
+================================================================================
+
+SDL's build system was traditionally based on autotools. Over time, this
+approach has suffered from several issues across the different supported
+platforms.
+To solve these problems, a new build system based on CMake is under development.
+It works in parallel to the legacy system, so users can experiment with it
+without complication.
+While still experimental, the build system should be usable on the following
+platforms:
+
+ * FreeBSD
+ * Linux
+ * VS.NET 2010
+ * MinGW and Msys
+ * OS X with support for XCode
+
+================================================================================
+Usage
+================================================================================
+
+Assuming the source for SDL is located at ~/sdl
+
+cd ~
+mkdir build
+cd build
+cmake ../sdl
+
+This will build the static and dynamic versions of SDL in the ~/build directory.

+SDL on DirectFB
+
+Supports:
+
+- Hardware YUV overlays
+- OpenGL - software only
+- 2D/3D accelerations (depends on directfb driver)
+- multiple displays
+- windows
+
+What you need:
+
+DirectFB 1.0.1, 1.2.x, 1.3.0
+Kernel-Framebuffer support: required: vesafb, radeonfb ....
+Mesa 7.0.x - optional for OpenGL
+
+/etc/directfbrc
+
+This file should contain the following lines to make
+your joystick work and avoid crashes:
+------------------------
+disable-module=joystick
+disable-module=cle266
+disable-module=cyber5k
+no-linux-input-grab
+------------------------
+
+To disable to use x11 backend when DISPLAY variable is found use
+
+export SDL_DIRECTFB_X11_CHECK=0
+
+To disable the use of linux input devices, i.e. multimice/multikeyboard support,
+use
+
+export SDL_DIRECTFB_LINUX_INPUT=0
+
+To use hardware accelerated YUV-overlays for YUV-textures, use:
+
+export SDL_DIRECTFB_YUV_DIRECT=1
+
+This is disabled by default. It will only support one
+YUV texture, namely the first. Every other YUV texture will be
+rendered in software.
+
+In addition, you may use (directfb-1.2.x)
+
+export SDL_DIRECTFB_YUV_UNDERLAY=1
+
+to make the YUV texture an underlay. This will make the cursor to
+be shown.
+
+Simple Window Manager
+=====================
+
+The driver has support for a very, very basic window manager you may
+want to use when running with "wm=default". Use
+
+export SDL_DIRECTFB_WM=1
+
+to enable basic window borders. In order to have the window title rendered,
+you need to have the following font installed:
+
+/usr/share/fonts/truetype/freefont/FreeSans.ttf
+
+OpenGL Support
+==============
+
+The following instructions will give you *software* OpenGL. However this
+works at least on all directfb supported platforms.
+
+As of this writing 20100802 you need to pull Mesa from git and do the following:
+
+------------------------
+git clone git://anongit.freedesktop.org/git/mesa/mesa
+cd mesa
+git checkout 2c9fdaf7292423c157fc79b5ce43f0f199dd753a

+Dollar Gestures
+===========================================================================
+SDL Provides an implementation of the $1 gesture recognition system. This allows for recording, saving, loading, and performing single stroke gestures.
+
+Gestures can be performed with any number of fingers (the centroid of the fingers must follow the path of the gesture), but the number of fingers must be constant (a finger cannot go down in the middle of a gesture). The path of a gesture is considered the path from the time when the final finger went down, to the first time any finger comes up.
+
+Dollar gestures are assigned an Id based on a hash function. This is guaranteed to remain constant for a given gesture. There is a (small) chance that two different gestures will be assigned the same ID. In this case, simply re-recording one of the gestures should result in a different ID.
+
+Recording:
+----------
+To begin recording on a touch device call:
+SDL_RecordGesture(SDL_TouchID touchId), where touchId is the id of the touch device you wish to record on, or -1 to record on all connected devices.
+
+Recording terminates as soon as a finger comes up. Recording is acknowledged by an SDL_DOLLARRECORD event.
+A SDL_DOLLARRECORD event is a dgesture with the following fields:
+
+event.dgesture.touchId - the Id of the touch used to record the gesture.
+event.dgesture.gestureId - the unique id of the recorded gesture.
+
+
+Performing:
+-----------
+As long as there is a dollar gesture assigned to a touch, every finger-up event will also cause an SDL_DOLLARGESTURE event with the following fields:
+
+event.dgesture.touchId - the Id of the touch which performed the gesture.
+event.dgesture.gestureId - the unique id of the closest gesture to the performed stroke.
+event.dgesture.error - the difference between the gesture template and the actual performed gesture. Lower error is a better match.
+event.dgesture.numFingers - the number of fingers used to draw the stroke.
+
+Most programs will want to define an appropriate error threshold and check to be sure that the error of a gesture is not abnormally high (an indicator that no gesture was performed).
+
+
+
+Saving:
+-------
+To save a template, call SDL_SaveDollarTemplate(gestureId, src) where gestureId is the id of the gesture you want to save, and src is an SDL_RWops pointer to the file where the gesture will be stored.
+
+To save all currently loaded templates, call SDL_SaveAllDollarTemplates(src) where source is an SDL_RWops pointer to the file where the gesture will be stored.
+
+Both functions return the number of gestures successfully saved.
+
+
+Loading:
+--------
+To load templates from a file, call SDL_LoadDollarTemplates(touchId,src) where touchId is the id of the touch to load to (or -1 to load to all touch devices), and src is an SDL_RWops pointer to a gesture save file.
+
+SDL_LoadDollarTemplates returns the number of templates successfully loaded.
+
+
+
+===========================================================================
+Multi Gestures
+===========================================================================
+SDL provides simple support for pinch/rotate/swipe gestures.
+Every time a finger is moved an SDL_MULTIGESTURE event is sent with the following fields:
+
+event.mgesture.touchId - the Id of the touch on which the gesture was performed.
+event.mgesture.x - the normalized x coordinate of the gesture. (0..1)
+event.mgesture.y - the normalized y coordinate of the gesture. (0..1)
+event.mgesture.dTheta - the amount that the fingers rotated during this motion.
+event.mgesture.dDist - the amount that the fingers pinched during this motion.
+event.mgesture.numFingers - the number of fingers used in the gesture.
+

+==============================================================================
+Building the Simple DirectMedia Layer for iPhone OS 2.0
+==============================================================================
+
+Requirements: Mac OS X v10.5 or later and the iPhone SDK.
+
+Instructions:
+1. Open SDL.xcodeproj (located in Xcode-iOS/SDL) in XCode.
+2. Select your desired target, and hit build.
+
+There are three build targets:
+- libSDL.a:
+ Build SDL as a statically linked library
+- testsdl
+ Build a test program (there are known test failures which are fine)
+- Template:
+ Package a project template together with the SDL for iPhone static libraries and copies of the SDL headers. The template includes proper references to the SDL library and headers, skeleton code for a basic SDL program, and placeholder graphics for the application icon and startup screen.
+
+==============================================================================
+Build SDL for iOS from the command line
+==============================================================================
+
+1. cd (PATH WHERE THE SDL CODE IS)/build-scripts
+2. ./iosbuild.sh
+
+If everything goes fine, you should see a build/ios directory, inside there's
+two directories "lib" and "include".
+"include" contains a copy of the SDL headers that you'll need for your project,
+make sure to configure XCode to look for headers there.
+"lib" contains find two files, libSDL2.a and libSDL2main.a, you have to add both
+to your XCode project. These libraries contain three architectures in them,
+armv6 for legacy devices, armv7, and i386 (for the simulator).
+By default, iosbuild.sh will autodetect the SDK version you have installed using
+xcodebuild -showsdks, and build for iOS >= 3.0, you can override this behaviour
+by setting the MIN_OS_VERSION variable, ie:
+
+MIN_OS_VERSION=4.2 ./iosbuild.sh
+
+==============================================================================
+Using the Simple DirectMedia Layer for iOS
+==============================================================================
+
+FIXME: This needs to be updated for the latest methods
+
+Here is the easiest method:
+1. Build the SDL libraries (libSDL.a and libSDLSimulator.a) and the iPhone SDL Application template.
+1. Install the iPhone SDL Application template by copying it to one of XCode's template directories. I recommend creating a directory called "SDL" in "/Developer/Platforms/iOS.platform/Developer/Library/XCode/Project Templates/" and placing it there.
+2. Start a new project using the template. The project should be immediately ready for use with SDL.
+
+Here is a more manual method:
+1. Create a new iPhone view based application.
+2. Build the SDL static libraries (libSDL.a and libSDLSimulator.a) for iPhone and include them in your project. XCode will ignore the library that is not currently of the correct architecture, hence your app will work both on iPhone and in the iPhone Simulator.
+3. Include the SDL header files in your project.
+4. Remove the ApplicationDelegate.h and ApplicationDelegate.m files -- SDL for iPhone provides its own UIApplicationDelegate. Remove MainWindow.xib -- SDL for iPhone produces its user interface programmatically.
+5. Delete the contents of main.m and program your app as a regular SDL program instead. You may replace main.m with your own main.c, but you must tell XCode not to use the project prefix file, as it includes Objective-C code.
+
+==============================================================================
+Notes -- Application events
+==============================================================================
+
+On iOS the application goes through a fixed life cycle and you will get
+notifications of state changes via application events. When these events
+are delivered you must handle them in an event callback because the OS may
+not give you any processing time after the events are delivered.
+
+e.g.
+
+int HandleAppEvents(void *userdata, SDL_Event *event)
+{
+ switch (event->type)
+ {
+ case SDL_APP_TERMINATING:
+ /* Terminate the app.
+ Shut everything down before returning from this function.
+ */
+ return 0;
+ case SDL_APP_LOWMEMORY:
+ /* You will get this when your app is paused and iOS wants more memory.
+ Release as much memory as possible.
+ */
+ return 0;
+ case SDL_APP_WILLENTERBACKGROUND:
+ /* Prepare your app to go into the background. Stop loops, etc.
+ This gets called when the user hits the home button, or gets a call.
+ */
+ return 0;
+ case SDL_APP_DIDENTERBACKGROUND:
+ /* This will get called if the user accepted whatever sent your app to the background.
+ If the user got a phone call and canceled it, you'll instead get an SDL_APP_DIDENTERFOREGROUND event and restart your loops.
+ When you get this, you have 5 seconds to save all your state or the app will be terminated.
+ Your app is NOT active at this point.
+ */
+ return 0;
+ case SDL_APP_WILLENTERFOREGROUND:
+ /* This call happens when your app is coming back to the foreground.
+ Restore all your state here.
+ */
+ return 0;
+ case SDL_APP_DIDENTERFOREGROUND:
+ /* Restart your loops here.
+ Your app is interactive and getting CPU again.
+ */
+ return 0;
+ default:
+ /* No special processing, add it to the event queue */
+ return 1;
+ }
+}
+
+int main(int argc, char *argv[])
+{
+ SDL_SetEventFilter(HandleAppEvents, NULL);
+
+ ... run your main loop
+
+ return 0;
+}
+
+
+==============================================================================
+Notes -- Accelerometer as Joystick
+==============================================================================
+
+SDL for iPhone supports polling the built in accelerometer as a joystick device. For an example on how to do this, see the accelerometer.c in the demos directory.
+
+The main thing to note when using the accelerometer with SDL is that while the iPhone natively reports accelerometer as floating point values in units of g-force, SDL_JoystickGetAxis reports joystick values as signed integers. Hence, in order to convert between the two, some clamping and scaling is necessary on the part of the iPhone SDL joystick driver. To convert SDL_JoystickGetAxis reported values BACK to units of g-force, simply multiply the values by SDL_IPHONE_MAX_GFORCE / 0x7FFF.
+
+==============================================================================
+Notes -- OpenGL ES
+==============================================================================
+
+Your SDL application for iPhone uses OpenGL ES for video by default.
+
+OpenGL ES for iPhone supports several display pixel formats, such as RGBA8 and RGB565, which provide a 32 bit and 16 bit color buffer respectively. By default, the implementation uses RGB565, but you may use RGBA8 by setting each color component to 8 bits in SDL_GL_SetAttribute.
+
+If your application doesn't use OpenGL's depth buffer, you may find significant performance improvement by setting SDL_GL_DEPTH_SIZE to 0.
+
+Finally, if your application completely redraws the screen each frame, you may find significant performance improvement by setting the attribute SDL_GL_RETAINED_BACKING to 1.
+
+==============================================================================
+Notes -- Keyboard
+==============================================================================
+
+The SDL keyboard API has been extended to support on-screen keyboards:
+
+void SDL_StartTextInput()
+ -- enables text events and reveals the onscreen keyboard.
+void SDL_StopTextInput()
+ -- disables text events and hides the onscreen keyboard.
+SDL_bool SDL_IsTextInputActive()
+ -- returns whether or not text events are enabled (and the onscreen keyboard is visible)
+
+==============================================================================
+Notes -- Reading and Writing files
+==============================================================================
+
+Each application installed on iPhone resides in a sandbox which includes its own Application Home directory. Your application may not access files outside this directory.
+
+Once your application is installed its directory tree looks like:
+
+MySDLApp Home/
+ MySDLApp.app
+ Documents/
+ Library/
+ Preferences/
+ tmp/
+
+When your SDL based iPhone application starts up, it sets the working directory to the main bundle (MySDLApp Home/MySDLApp.app), where your application resources are stored. You cannot write to this directory. Instead, I advise you to write document files to "../Documents/" and preferences to "../Library/Preferences".
+
+More information on this subject is available here:
+http://developer.apple.com/library/ios/#documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/Introduction/Introduction.html
+
+==============================================================================
+Notes -- iPhone SDL limitations
+==============================================================================
+
+Windows:
+ Full-size, single window applications only. You cannot create multi-window SDL applications for iPhone OS. The application window will fill the display, though you have the option of turning on or off the menu-bar (pass SDL_CreateWindow the flag SDL_WINDOW_BORDERLESS).
+
+Textures:
+ The optimal texture formats on iOS are SDL_PIXELFORMAT_ABGR8888, SDL_PIXELFORMAT_ABGR8888, SDL_PIXELFORMAT_BGR888, and SDL_PIXELFORMAT_RGB24 pixel formats.
+
+Loading Shared Objects:
+ This is disabled by default since it seems to break the terms of the iPhone SDK agreement. It can be re-enabled in SDL_config_iphoneos.h.
+
+==============================================================================
+Game Center
+==============================================================================
+
+Game Center integration requires that you break up your main loop in order to yield control back to the system. In other words, instead of running an endless main loop, you run each frame in a callback function, using:
+
+int SDL_iPhoneSetAnimationCallback(SDL_Window * window, int interval, void (*callback)(void*), void *callbackParam);
+
+This will set up the given function to be called back on the animation callback, and then you have to return from main() to let the Cocoa event loop run.
+
+e.g.
+
+extern "C"
+void ShowFrame(void*)
+{
+ ... do event handling, frame logic and rendering
+}
+
+int main(int argc, char *argv[])
+{
+ ... initialize game ...
+
+#if __IPHONEOS__
+ // Initialize the Game Center for scoring and matchmaking
+ InitGameCenter();
+
+ // Set up the game to run in the window animation callback on iOS
+ // so that Game Center and so forth works correctly.
+ SDL_iPhoneSetAnimationCallback(window, 1, ShowFrame, NULL);
+#else
+ while ( running ) {
+ ShowFrame(0);
+ DelayFrame();
+ }
+#endif
+ return 0;
+}

+==============================================================================
+Using the Simple DirectMedia Layer with Mac OS X
+==============================================================================
+
+These instructions are for people using Apple's Mac OS X (pronounced
+"ten").
+
+From the developer's point of view, OS X is a sort of hybrid Mac and
+Unix system, and you have the option of using either traditional
+command line tools or Apple's IDE Xcode.
+
+To build SDL using the command line, use the standard configure and make
+process:
+
+ ./configure
+ make
+ sudo make install
+
+You can also build SDL as a Universal library (a single binary for both
+PowerPC and Intel architectures), on Mac OS X 10.4 and newer, by using
+the fatbuild.sh script in build-scripts:
+ sh build-scripts/fatbuild.sh
+ sudo build-scripts/fatbuild.sh install
+This script builds SDL with 10.2 ABI compatibility on PowerPC and 10.4
+ABI compatibility on Intel architectures. For best compatibility you
+should compile your application the same way. A script which wraps
+gcc to make this easy is provided in test/gcc-fat.sh
+
+To use the library once it's built, you essential have two possibilities:
+use the traditional autoconf/automake/make method, or use Xcode.
+
+==============================================================================
+Using the Simple DirectMedia Layer with a traditional Makefile
+==============================================================================
+
+An existing autoconf/automake build system for your SDL app has good chances
+to work almost unchanged on OS X. However, to produce a "real" Mac OS X binary
+that you can distribute to users, you need to put the generated binary into a
+so called "bundle", which basically is a fancy folder with a name like
+"MyCoolGame.app".
+
+To get this build automatically, add something like the following rule to
+your Makefile.am:
+
+bundle_contents = APP_NAME.app/Contents
+APP_NAME_bundle: EXE_NAME
+ mkdir -p $(bundle_contents)/MacOS
+ mkdir -p $(bundle_contents)/Resources
+ echo "APPL????" > $(bundle_contents)/PkgInfo
+ $(INSTALL_PROGRAM) $< $(bundle_contents)/MacOS/
+
+You should replace EXE_NAME with the name of the executable. APP_NAME is what
+will be visible to the user in the Finder. Usually it will be the same
+as EXE_NAME but capitalized. E.g. if EXE_NAME is "testgame" then APP_NAME
+usually is "TestGame". You might also want to use @PACKAGE@ to use the package
+name as specified in your configure.in file.
+
+If your project builds more than one application, you will have to do a bit
+more. For each of your target applications, you need a separate rule.
+
+If you want the created bundles to be installed, you may want to add this
+rule to your Makefile.am:
+
+install-exec-hook: APP_NAME_bundle
+ rm -rf $(DESTDIR)$(prefix)/Applications/APP_NAME.app
+ mkdir -p $(DESTDIR)$(prefix)/Applications/
+ cp -r $< /$(DESTDIR)$(prefix)Applications/
+
+This rule takes the Bundle created by the rule from step 3 and installs them
+into $(DESTDIR)$(prefix)/Applications/.
+
+Again, if you want to install multiple applications, you will have to augment
+the make rule accordingly.
+
+
+But beware! That is only part of the story! With the above, you end up with
+a bare bone .app bundle, which is double clickable from the Finder. But
+there are some more things you should do before shipping your product...
+
+1) The bundle right now probably is dynamically linked against SDL. That
+ means that when you copy it to another computer, *it will not run*,
+ unless you also install SDL on that other computer. A good solution
+ for this dilemma is to static link against SDL. On OS X, you can
+ achieve that by linking against the libraries listed by
+ sdl-config --static-libs
+ instead of those listed by
+ sdl-config --libs
+ Depending on how exactly SDL is integrated into your build systems, the
+ way to achieve that varies, so I won't describe it here in detail
+2) Add an 'Info.plist' to your application. That is a special XML file which
+ contains some meta-information about your application (like some copyright
+ information, the version of your app, the name of an optional icon file,
+ and other things). Part of that information is displayed by the Finder
+ when you click on the .app, or if you look at the "Get Info" window.
+ More information about Info.plist files can be found on Apple's homepage.
+
+
+As a final remark, let me add that I use some of the techniques (and some
+variations of them) in Exult and ScummVM; both are available in source on
+the net, so feel free to take a peek at them for inspiration!
+
+
+==============================================================================
+Using the Simple DirectMedia Layer with Xcode
+==============================================================================
+
+These instructions are for using Apple's Xcode IDE to build SDL applications.
+
+- First steps
+
+The first thing to do is to unpack the Xcode.tar.gz archive in the
+top level SDL directory (where the Xcode.tar.gz archive resides).
+Because Stuffit Expander will unpack the archive into a subdirectory,
+you should unpack the archive manually from the command line:
+ cd [path_to_SDL_source]
+ tar zxf Xcode.tar.gz
+This will create a new folder called Xcode, which you can browse
+normally from the Finder.
+
+- Building the Framework
+
+The SDL Library is packaged as a framework bundle, an organized
+relocatable folder hierarchy of executable code, interface headers,
+and additional resources. For practical purposes, you can think of a
+framework as a more user and system-friendly shared library, whose library
+file behaves more or less like a standard UNIX shared library.
+
+To build the framework, simply open the framework project and build it.
+By default, the framework bundle "SDL.framework" is installed in
+/Library/Frameworks. Therefore, the testers and project stationary expect
+it to be located there. However, it will function the same in any of the
+following locations:
+
+ ~/Library/Frameworks
+ /Local/Library/Frameworks
+ /System/Library/Frameworks
+
+- Build Options
+ There are two "Build Styles" (See the "Targets" tab) for SDL.
+ "Deployment" should be used if you aren't tweaking the SDL library.
+ "Development" should be used to debug SDL apps or the library itself.
+
+- Building the Testers
+ Open the SDLTest project and build away!
+
+- Using the Project Stationary
+ Copy the stationary to the indicated folders to access it from
+ the "New Project" and "Add target" menus. What could be easier?
+
+- Setting up a new project by hand
+ Some of you won't want to use the Stationary so I'll give some tips:
+ * Create a new "Cocoa Application"
+ * Add src/main/macosx/SDLMain.m , .h and .nib to your project
+ * Remove "main.c" from your project
+ * Remove "MainMenu.nib" from your project
+ * Add "$(HOME)/Library/Frameworks/SDL.framework/Headers" to include path
+ * Add "$(HOME)/Library/Frameworks" to the frameworks search path
+ * Add "-framework SDL -framework Foundation -framework AppKit" to "OTHER_LDFLAGS"
+ * Set the "Main Nib File" under "Application Settings" to "SDLMain.nib"
+ * Add your files
+ * Clean and build
+
+- Building from command line
+ Use pbxbuild in the same directory as your .pbproj file
+
+- Running your app
+ You can send command line args to your app by either invoking it from
+ the command line (in *.app/Contents/MacOS) or by entering them in the
+ "Executables" panel of the target settings.
+
+- Implementation Notes
+ Some things that may be of interest about how it all works...
+ * Working directory
+ As defined in the SDL_main.m file, the working directory of your SDL app
+ is by default set to its parent. You may wish to change this to better
+ suit your needs.
+ * You have a Cocoa App!
+ Your SDL app is essentially a Cocoa application. When your app
+ starts up and the libraries finish loading, a Cocoa procedure is called,
+ which sets up the working directory and calls your main() method.
+ You are free to modify your Cocoa app with generally no consequence
+ to SDL. You cannot, however, easily change the SDL window itself.
+ Functionality may be added in the future to help this.
+

+SDL 2.0 with open pandora console support ( http://openpandora.org/ )
+=====================================================================
+
+- A pandora specific video driver was written to allow SDL 2.0 with OpenGL ES
+support to work on the pandora under the framebuffer. This driver do not have

+The video driver name is "pandora" so if you have problem running it from

+
+* Porting To A New Platform
+
+ The first thing you have to do when porting to a new platform, is look at
+include/SDL_platform.h and create an entry there for your operating system.
+The standard format is __PLATFORM__, where PLATFORM is the name of the OS.
+Ideally SDL_platform.h will be able to auto-detect the system it's building
+on based on C preprocessor symbols.
+
+There are two basic ways of building SDL at the moment:
+
+1. The "UNIX" way: ./configure; make; make install
+
+ If you have a GNUish system, then you might try this. Edit configure.in,
+ take a look at the large section labelled:
+ "Set up the configuration based on the target platform!"
+ Add a section for your platform, and then re-run autogen.sh and build!
+
+2. Using an IDE:
+
+ If you're using an IDE or other non-configure build system, you'll probably
+ want to create a custom SDL_config.h for your platform. Edit SDL_config.h,
+ add a section for your platform, and create a custom SDL_config_{platform}.h,
+ based on SDL_config.h.minimal and SDL_config.h.in
+
+ Add the top level include directory to the header search path, and then add
+ the following sources to the project:
+ src/*.c
+ src/atomic/*.c
+ src/audio/*.c
+ src/cpuinfo/*.c
+ src/events/*.c
+ src/file/*.c
+ src/haptic/*.c
+ src/joystick/*.c
+ src/power/*.c
+ src/render/*.c
+ src/stdlib/*.c
+ src/thread/*.c
+ src/timer/*.c
+ src/video/*.c
+ src/audio/disk/*.c
+ src/audio/dummy/*.c
+ src/video/dummy/*.c
+ src/haptic/dummy/*.c
+ src/joystick/dummy/*.c
+ src/main/dummy/*.c
+ src/thread/generic/*.c
+ src/timer/dummy/*.c
+ src/loadso/dummy/*.c
+
+
+Once you have a working library without any drivers, you can go back to each
+of the major subsystems and start implementing drivers for your platform.
+
+If you have any questions, don't hesitate to ask on the SDL mailing list:
+ http://www.libsdl.org/mailing-list.php
+
+Enjoy!

+===========================================================================
+System Specific Notes
+===========================================================================
+Linux:
+The linux touch system is currently based off event streams, and proc/bus/devices. The active user must be given permissions to read /dev/input/TOUCHDEVICE, where TOUCHDEVICE is the event stream for your device. Currently only Wacom tablets are supported. If you have an unsupported tablet contact me at jim.tla+sdl_touch@gmail.com and I will help you get support for it.
+
+Mac:
+The Mac and iPhone APIs are pretty. If your touch device supports them then you'll be fine. If it doesn't, then there isn't much we can do.
+
+iPhone:
+Works out of box.
+
+Windows:
+Unfortunately there is no windows support as of yet. Support for Windows 7 is planned, but we currently have no way to test. If you have a Windows 7 WM_TOUCH supported device, and are willing to help test please contact me at jim.tla+sdl_touch@gmail.com
+
+===========================================================================
+Events
+===========================================================================
+SDL_FINGERDOWN:
+Sent when a finger (or stylus) is placed on a touch device.
+Fields:
+event.tfinger.touchId - the Id of the touch device.
+event.tfinger.fingerId - the Id of the finger which just went down.
+event.tfinger.x - the x coordinate of the touch (0..1)
+event.tfinger.y - the y coordinate of the touch (0..1)
+event.tfinger.pressure - the pressure of the touch (0..1)
+
+SDL_FINGERMOTION:
+Sent when a finger (or stylus) is moved on the touch device.
+Fields:
+Same as SDL_FINGERDOWN but with additional:
+event.tfinger.dx - change in x coordinate during this motion event.
+event.tfinger.dy - change in y coordinate during this motion event.
+
+SDL_FINGERUP:
+Sent when a finger (or stylus) is lifted from the touch device.
+Fields:
+Same as SDL_FINGERDOWN.
+
+
+===========================================================================
+Functions
+===========================================================================
+SDL provides the ability to access the underlying Finger structures.
+These structures should _never_ be modified.
+
+The following functions are included from SDL_touch.h
+
+To get a SDL_TouchID call SDL_GetTouchDevice(index).
+This returns a SDL_TouchID.
+IMPORTANT: If the touch has been removed, or there is no touch with the given ID, SDL_GetTouchID will return 0. Be sure to check for this!
+
+The number of touch devices can be queried with SDL_GetNumTouchDevices().
+
+A SDL_TouchID may be used to get pointers to SDL_Finger.
+
+SDL_GetNumTouchFingers(touchID) may be used to get the number of fingers currently down on the device.
+
+The most common reason to access SDL_Finger is to query the fingers outside the event. In most cases accessing the fingers is using the event. This would be accomplished by code like the following:
+
+ float x = event.tfinger.x;
+ float y = event.tfinger.y;
+
+
+
+To get a SDL_Finger, call SDL_GetTouchFinger(touchID,index), where touchID is a SDL_TouchID, and index is the requested finger.
+This returns a SDL_Finger*, or NULL if the finger does not exist, or has been removed.
+A SDL_Finger is guaranteed to be persistent for the duration of a touch, but it will be de-allocated as soon as the finger is removed. This occurs when the SDL_FINGERUP event is _added_ to the event queue, and thus _before_ the SDL_FINGERUP event is polled.
+As a result, be very careful to check for NULL return values.
+
+A SDL_Finger has the following fields:
+>x,y,pressure:
+ The current coordinates of the touch.
+>pressure:
+ The pressure of the touch.
+

+ Simple DirectMedia Layer
+
+ (SDL)
+
+ Version 2.0
+
+---
+http://www.libsdl.org/
+
+Simple DirectMedia Layer is a cross-platform development library designed
+to provide low level access to audio, keyboard, mouse, joystick, and graphics
+hardware via OpenGL and Direct3D. It is used by video playback software,
+emulators, and popular games including Valve's award winning catalog
+and many Humble Bundle games.
+
+SDL officially supports Windows, Mac OS X, Linux, iOS, and Android.
+Support for other platforms may be found in the source code.
+
+SDL is written in C, works natively with C++, and there are bindings
+available for several other languages, including C# and Python.
+
+This library is distributed under the zlib license, which can be found
+in the file "COPYING.txt".
+
+The best way to learn how to use SDL is to check out the header files in
+the "include" subdirectory and the programs in the "test" subdirectory.
+The header files and test programs are well commented and always up to date.
+More documentation and FAQs are available online at:
+ http://wiki.libsdl.org/
+
+If you need help with the library, or just want to discuss SDL related
+issues, you can join the developers mailing list:
+ http://www.libsdl.org/mailing-list.php
+
+Enjoy!

+ <H3>
+ Building SDL
+ </H3>
+ <P>
+ Go into the VisualC directory and double-click on the Visual Studio solution for your version of Visual Studio, e.g. <CODE>SDL_VS2008.sln</CODE> This should open up the IDE.
+ </P>
+ <P>
+ There are different solution files for the various

+ 2008, 2010 or 2012; the 2010EE and 2012EE files
+ should be used with the "Express Edition" releases.
+ </P>
+ <P>
+ Build the <CODE>.dll</CODE> and <CODE>.lib</CODE> files.
+ </P>
+ <P>
+ This is done by right clicking on each project in turn (Projects are listed in
+ the Workspace panel in the FileView tab), and selecting "Build".
+ </P>
+ <P>
+ You may get a few warnings, but you should not get any errors. You do have to
+ have at least the DirectX 9 SDK installed, however. The latest

+ <P>
+ Later, we will refer to the following .lib and .dll files that have just been

+==============================================================================
+About the iPhone OS Demo Applications
+==============================================================================
+
+Demos.xcodeproj contains several targets for iPhone oriented SDL demos. These demos are written strictly using SDL 1.3 calls. All the demos except for Fireworks (which requires OpenGL ES) should work on platforms other than iPhone OS, though you'll need to write your own compile script. To run them on your favorite platform, you may wish to set the macros SCREEN_WIDTH and SCREEN_HEIGHT, located in common.h.
+
+Common files:
+
+ common.c and common.h contain code common to all demo applications. This includes macros about the screen dimensions (in pixels), simple error handling, and functions for generating random numbers.
+
+Rectangles (rectangles.c):
+
+ Draws randomly sized and colored rectangles all over the screen by using SDL_RenderFill. This is the simplest of all the demos.
+
+Happy (happy.c):
+
+ Loads the classic happy-face bitmap and draws a large number of happy faces bouncing around the screen. Shows how you can load a bitmap into an SDL_Texture.
+
+Accelerometer (accelerometer.c):
+
+ Uses the iPhone's accelerometer as a joystick device to move a spaceship around the screen. Note the use of the macro SDL_IPHONE_MAX_GFORCE (normally defined in SDL_config_iphoneos.h) which converts between the Sint16 number returned by SDL_JoystickGetAxis, and the floating point units of g-force reported natively by the iPhone.
+
+Touch (touch.c):
+
+ Acts as a finger-paint type program. Demonstrates how you can use SDL mouse input to accept touch input from the iPhone. If SDL for iPhone is compiled with multitouch as multiple mouse emulation (SDL_IPHONE_MULTIPLE_MICE in SDL_config_iphoneos.h) then the program will accept multiple finger inputs simultaneously.
+
+Mixer (mixer.c):
+
+ Displays several rectangular buttons which can be used as a virtual drumkit. Demonstrates how you can play .wav sounds in SDL and how you can use SDL_MixAudioFormat to build a software mixer that can play multiple sounds at once.
+
+Keyboard (keyboard.c):
+
+ Loads a bitmap font and let's the user type words, numbers, and symbols using the iPhone's virtual keyboard. The iPhone's onscreen keyboard visibility is toggled when the user taps the screen. If the user types ':)' a happy face is displayed. Demonstrates how to use functions added to the iPhone implementation of SDL to toggle keyboard onscreen visibility.
+
+Fireworks (fireworks.c):
+
+ Displays a fireworks show. When you tap the iPhone's screen, fireworks fly from the bottom of the screen and explode at the point that you tapped. Demonstrates how you can use SDL on iPhone to build an OpenGL ES based application. Shows you how you can use SDL_LoadBMP to load a bmp image and convert it to an OpenGL ES texture. Of lesser importance, shows how you can use OpenGL ES point sprites to build an efficient particle system.
+
+==============================================================================
+Building and Running the demos
+==============================================================================
+
+Before building the demos you must first build SDL as a static library for BOTH the iPhone Simulator and the iPhone itself. See the iPhone SDL main README file for directions on how to do this. Once this is done, simply launch XCode, select the target you'd like to build, select the active SDK (simulator or device), and then build and go.

+"Recipient" means anyone who receives the Program under this Agreement,
+including all Contributors.
+
+2. GRANT OF RIGHTS
+
+ a) Subject to the terms of this Agreement, each Contributor hereby
+ grants Recipient a non-exclusive, worldwide, royalty-free copyright
+ license to reproduce, prepare derivative works of, publicly display,
+ publicly perform, distribute and sublicense the Contribution of such
+ Contributor, if any, and such derivative works, in source code and
+ object code form.
+
+ b) Subject to the terms of this Agreement, each Contributor hereby
+ grants Recipient a non-exclusive, worldwide, royalty-free patent
+ license under Licensed Patents to make, use, sell, offer to sell,
+ import and otherwise transfer the Contribution of such Contributor,
+ if any, in source code and object code form. This patent license
+ shall apply to the combination of the Contribution and the Program
+ if, at the time the Contribution is added by the Contributor, such
+ addition of the Contribution causes such combination to be covered
+ by the Licensed Patents. The patent license shall not apply to any
+ other combinations which include the Contribution. No hardware per
+ se is licensed hereunder.
+
+ c) Recipient understands that although each Contributor grants the
+ licenses to its Contributions set forth herein, no assurances are
+ provided by any Contributor that the Program does not infringe the
+ patent or other intellectual property rights of any other entity.
+ Each Contributor disclaims any liability to Recipient for claims
+ brought by any other entity based on infringement of intellectual
+ property rights or otherwise. As a condition to exercising the
+ rights and licenses granted hereunder, each Recipient hereby assumes
+ sole responsibility to secure any other intellectual property rights
+ needed, if any. For example, if a third party patent license is
+ required to allow Recipient to distribute the Program, it is
+ Recipient's responsibility to acquire that license before
+ distributing the Program.
+
+ d) Each Contributor represents that to its knowledge it has
+ sufficient copyright rights in its Contribution, if any, to grant
+ the copyright license set forth in this Agreement.
+
+3. REQUIREMENTS
+
+A Contributor may choose to distribute the Program in object code form
+under its own license agreement, provided that:
+
+ a) it complies with the terms and conditions of this Agreement; and
+
+ b) its license agreement:
+
+ i) effectively disclaims on behalf of all Contributors all
+ warranties and conditions, express and implied, including warranties
+ or conditions of title and non-infringement, and implied warranties
+ or conditions of merchantability and fitness for a particular
+ purpose;
+
+ ii) effectively excludes on behalf of all Contributors all liability
+ for damages, including direct, indirect, special, incidental and
+ consequential damages, such as lost profits;
+
+ iii) states that any provisions which differ from this Agreement are
+ offered by that Contributor alone and not by any other party; and
+
+ iv) states that source code for the Program is available from such
+ Contributor, and informs licensees how to obtain it in a reasonable
+ manner on or through a medium customarily used for software
+ exchange.
+
+When the Program is made available in source code form:
+
+ a) it must be made available under this Agreement; and
+
+ b) a copy of this Agreement must be included with each copy of the
+ Program.
+
+Contributors may not remove or alter any copyright notices contained
+within the Program.
+
+Each Contributor must identify itself as the originator of its
+Contribution, if any, in a manner that reasonably allows subsequent
+Recipients to identify the originator of the Contribution.
+
+4. COMMERCIAL DISTRIBUTION
+
+Commercial distributors of software may accept certain responsibilities
+with respect to end users, business partners and the like. While this
+license is intended to facilitate the commercial use of the Program, the
+Contributor who includes the Program in a commercial product offering
+should do so in a manner which does not create potential liability for
+other Contributors. Therefore, if a Contributor includes the Program in
+a commercial product offering, such Contributor ("Commercial
+Contributor") hereby agrees to defend and indemnify every other
+Contributor ("Indemnified Contributor") against any losses, damages and
+costs (collectively "Losses") arising from claims, lawsuits and other
+legal actions brought by a third party against the Indemnified
+Contributor to the extent caused by the acts or omissions of such
+Commercial Contributor in connection with its distribution of the
+Program in a commercial product offering. The obligations in this
+section do not apply to any claims or Losses relating to any actual or
+alleged intellectual property infringement. In order to qualify, an
+Indemnified Contributor must: a) promptly notify the Commercial
+Contributor in writing of such claim, and b) allow the Commercial
+Contributor to control, and cooperate with the Commercial Contributor
+in, the defense and any related settlement negotiations. The Indemnified
+Contributor may participate in any such claim at its own expense.
+
+For example, a Contributor might include the Program in a commercial
+product offering, Product X. That Contributor is then a Commercial
+Contributor. If that Commercial Contributor then makes performance
+claims, or offers warranties related to Product X, those performance
+claims and warranties are such Commercial Contributor's responsibility
+alone. Under this section, the Commercial Contributor would have to
+defend claims against the other Contributors related to those
+performance claims and warranties, and if a court requires any other
+Contributor to pay any damages as a result, the Commercial Contributor
+must pay those damages.
+
+5. NO WARRANTY
+
+EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED
+ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND,
+EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES
+OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR
+A PARTICULAR PURPOSE. Each Recipient is solely responsible for
+determining the appropriateness of using and distributing the Program
+and assumes all risks associated with its exercise of rights under this
+Agreement, including but not limited to the risks and costs of program
+errors, compliance with applicable laws, damage to or loss of data,
+programs or equipment, and unavailability or interruption of operations.
+
+6. DISCLAIMER OF LIABILITY
+
+EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR
+ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,
+INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING
+WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
+LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING
+NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR
+DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED
+HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+7. GENERAL
+
+If any provision of this Agreement is invalid or unenforceable under
+applicable law, it shall not affect the validity or enforceability of
+the remainder of the terms of this Agreement, and without further action
+by the parties hereto, such provision shall be reformed to the minimum
+extent necessary to make such provision valid and enforceable.
+
+If Recipient institutes patent litigation against a Contributor with
+respect to a patent applicable to software (including a cross-claim or
+counterclaim in a lawsuit), then any patent licenses granted by that
+Contributor to such Recipient under this Agreement shall terminate as of
+the date such litigation is filed. In addition, if Recipient institutes
+patent litigation against any entity (including a cross-claim or
+counterclaim in a lawsuit) alleging that the Program itself (excluding
+combinations of the Program with other software or hardware) infringes
+such Recipient's patent(s), then such Recipient's rights granted under
+Section 2(b) shall terminate as of the date such litigation is filed.
+
+All Recipient's rights under this Agreement shall terminate if it fails
+to comply with any of the material terms or conditions of this Agreement
+and does not cure such failure in a reasonable period of time after
+becoming aware of such noncompliance. If all Recipient's rights under
+this Agreement terminate, Recipient agrees to cease use and distribution
+of the Program as soon as reasonably practicable. However, Recipient's
+obligations under this Agreement and any licenses granted by Recipient
+relating to the Program shall continue and survive.
+
+Everyone is permitted to copy and distribute copies of this Agreement,
+but in order to avoid inconsistency the Agreement is copyrighted and may
+only be modified in the following manner. The Agreement Steward reserves
+the right to publish new versions (including revisions) of this
+Agreement from time to time. No one other than the Agreement Steward has
+the right to modify this Agreement. IBM is the initial Agreement
+Steward. IBM may assign the responsibility to serve as the Agreement
+Steward to a suitable separate entity. Each new version of the Agreement
+will be given a distinguishing version number. The Program (including
+Contributions) may always be distributed subject to the version of the
+Agreement under which it was received. In addition, after a new version
+of the Agreement is published, Contributor may elect to distribute the
+Program (including its Contributions) under the new version. Except as
+expressly stated in Sections 2(a) and 2(b) above, Recipient receives no
+rights or licenses to the intellectual property of any Contributor under
+this Agreement, whether expressly, by implication, estoppel or
+otherwise. All rights in the Program not expressly granted under this
+Agreement are reserved.
+
+This Agreement is governed by the laws of the State of New York and the
+intellectual property laws of the United States of America. No party to
+this Agreement will bring a legal action under this Agreement more than
+one year after the cause of action arose. Each party waives its rights
+to a jury trial in any resulting litigation.

+TestiPhoneOS.xcodeproj contains targets to compile many of the SDL test programs for iPhone OS. Most of these test programs work fine, with the following exceptions:
+
+testalpha:
+ Program crashes. Problem appears to effect Mac OS X as well.
+
+testthread:
+ SIGTERM kills the process immediately without executing the 'kill' function. The posix standard says this shouldn't happen. Apple seems intent on having iPhone apps exit promptly when the user requests it, so maybe that's why(?)
+
+testlock:
+ Locks appear to work, but there doesn't appear to be a simple way to send the process SIGINT.
+
+testpalette:
+ "SDL error: blitting boat: Blit combination not supported." Happens on Mac OS X as well.
+
+testsprite2:
+ SDL_CreateTextureFromSurface requests an ARGB pixel format, but iPhone's SDL video driver only supports ABGR.
+
+testwin:
+ Behaves as it does under Mac OS X ... not sure if that is correctly or not.
+
+threadwin:
+ Works if -threaded is not on. Otherwise it doesn't work, but this is true under Mac OS X as well.

+ comments = "To build Universal Binaries, we have experimented with a variety of different options.\nThe complication is that we must retain compatibility with at least 10.2. \nThe Universal Binary defaults only work for > 10.3.9\n\nSo far, we have found:\ngcc 4.0.0 with Xcode 2.1 always links against libgcc_s. gcc 4.0.1 from Xcode 2.2 fixes this problem.\n\nBut gcc 4.0 will not work with < 10.3.9 because we continue to get an undefined symbol to _fprintf$LDBL128.\nSo we must use gcc 3.3 on PPC to accomplish 10.2 support. (But 4.0 is required for i386.)\n\nSetting the deployment target to 10.4 will disable prebinding, so for PPC, we set it less than 10.4 to preserve prebinding for legacy support.\n\nSetting the PPC SDKROOT to /Developers/SDKs/MacOSX10.2.8.sdk will link to 63.0.0 libSystem.B.dylib. Leaving it at current or 10.4u links to 88.1.2. However, as long as we are using gcc 3.3, it doesn't seem to matter as testing has demonstrated both will run. We have decided not to invoke the 10.2.8 SDK because it is not a default installed component with Xcode which will probably cause most people problems. However, rather than deleting the SDKROOT_ppc entry entirely, we have mapped it to 10.4u in case we decide we need to change this setting.\n\nTo use Altivec or SSE, we needed architecture specific flags:\nOTHER_CFLAGS_ppc\nOTHER_CFLAGS_i386\nOTHER_CFLAGS=$(OTHER_CFLAGS_($CURRENT_ARCH))\n\nThe general OTHER_CFLAGS needed to be manually mapped to architecture specific options because Xcode didn't do this automatically for us.\n\n\n";

You can also manually add \"-framework SDL\" to your linker flags if you don't like the check box system.\n\nAdd /Library/Frameworks/SDL.framework/Headers to your header search path\nAdd /Library/Frameworks to your library search path\n(Adjust the two above if installed in $(HOME)/Library/Frameworks. You can also list both paths if you want robustness.)\n\nWe used to use an exports file. It was becoming a maintenance issue we kept neglecting, so we have removed it. If you need it back, set the \"Exported Symbols File\" option to:\n../../src/main/macosx/exports/SDL.x\n(You may need to regenerate the exports list. There is a Makefile in that directory that you can run from the command line to rebuild it.)\nLong term, we want to utilize gcc 4.0's new visibility feature (analogous to declspec on Windows). Other platforms would benefit from this change too. The downside is that we still use gcc 3.3 for the PowerPC build here so only our x86 builds will cull the symbols if we go down this route (and don't use the exports file).\n\n";

+The Simple DirectMedia Layer (SDL for short) is a cross-platform
+library designed to make it easy to write multi-media software,
+such as games and emulators.
+
+The Simple DirectMedia Layer library source code is available from:
+http://www.libsdl.org/
+
+This library is distributed under the terms of the zlib license:
+http://zlib.net/zlib_license.html
+
+
+This packages contains the SDL framework for OS X.
+Conforming with Apple guidelines, this framework
+contains both the SDL runtime component and development header files.
+
+
+To Install:
+Copy the SDL2.framework to /Library/Frameworks
+
+You may alternatively install it in <Your home directory>/Library/Frameworks
+if your access privileges are not high enough.
+
+
+Additional References:
+
+ - Screencast tutorials for getting started with OpenSceneGraph/Mac OS X are
+ available at:
+ http://www.openscenegraph.org/projects/osg/wiki/Support/Tutorials/MacOSXTips
+ Though these are OpenSceneGraph centric, the same exact concepts apply to
+ SDL, thus the videos are recommended for everybody getting started with
+ developing on Mac OS X. (You can skim over the PlugIns stuff since SDL
+ doesn't have any PlugIns to worry about.)

+ comments = "I made these tests link against our \"default\" framework which includes X11 stuff. If you didn't install the X11 headers with Xcode, you might have problems building the SDL.framework (which is a dependency). You can swap the dependencies around to get around this, or you can modify the default SDL.framework target to not include X11 stuff. (Go into its target build options and remove all the Preprocessor macros.)\n\n\n\nWe are sort of in a half-way state at the moment. Going \"all-the-way\" means we copy the SDL.framework inside the app bundle so we can run the test without the step of the user \"installing\" the framework. But there is an oversight/bug in Xcode that doesn't correctly find the location of the framework when in an embedded/nested Xcode project. We could probably try to hack this with a shell script that checks multiple directories for existence, but this is messier and more work than I prefer, so I rather just wait for Apple to fix this. In the meantime...\n\nThe \"All\" target will build the SDL framework from the Xcode project. The other targets do not have this dependency set (for flexibility reasons in case we make changes). If you have not built the framework, you will probably be unable to link. You will either need to build the framework, or you need to add \"-framework SDL\" to the link options and make sure you have the SDL.framework installed somewhere where it can be seen (like /Library/Frameworks...I think we already set this one up.) \n\nTo run though, you should have a copy of the SDL.framework in /Library/Frameworks or ~/Library/Frameworks.\n\n\n\n\ntestgl and testdyngl need -DHAVE_OPENGL\ntestgl needs to link against OpenGL.framework\n\n";

+# AX_GCC_ARCHFLAG([PORTABLE?], [ACTION-SUCCESS], [ACTION-FAILURE])
+#
+# DESCRIPTION
+#
+# This macro tries to guess the "native" arch corresponding to the target
+# architecture for use with gcc's -march=arch or -mtune=arch flags. If
+# found, the cache variable $ax_cv_gcc_archflag is set to this flag and
+# ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is is set to
+# "unknown" and ACTION-FAILURE is executed. The default ACTION-SUCCESS is
+# to add $ax_cv_gcc_archflag to the end of $CFLAGS.
+#
+# PORTABLE? should be either [yes] (default) or [no]. In the former case,
+# the flag is set to -mtune (or equivalent) so that the architecture is
+# only used for tuning, but the instruction set used is still portable. In
+# the latter case, the flag is set to -march (or equivalent) so that
+# architecture-specific instructions are enabled.
+#
+# The user can specify --with-gcc-arch=<arch> in order to override the
+# macro's choice of architecture, or --without-gcc-arch to disable this.
+#
+# When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is
+# called unless the user specified --with-gcc-arch manually.
+#
+# Requires macros: AX_CHECK_COMPILER_FLAGS, AX_GCC_X86_CPUID
+#
+# (The main emphasis here is on recent CPUs, on the principle that doing
+# high-performance computing on old hardware is uncommon.)

+# SYNOPSIS
+#
+# AX_GCC_X86_CPUID(OP)
+#
+# DESCRIPTION
+#
+# On Pentium and later x86 processors, with gcc or a compiler that has a
+# compatible syntax for inline assembly instructions, run a small program
+# that executes the cpuid instruction with input OP. This can be used to
+# detect the CPU type.
+#
+# On output, the values of the eax, ebx, ecx, and edx registers are stored
+# as hexadecimal strings as "eax:ebx:ecx:edx" in the cache variable
+# ax_cv_gcc_x86_cpuid_OP.
+#
+# If the cpuid instruction fails (because you are running a
+# cross-compiler, or because you are not using gcc, or because you are on
+# a processor that doesn't have this instruction), ax_cv_gcc_x86_cpuid_OP
+# is set to the string "unknown".
+#
+# This macro mainly exists to be used in AX_GCC_ARCHFLAG.

+
+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else. This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.
+
+# This is to help aclocal find these macros, as it can't see m4_define.

+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]

+ - Update Build-Depends:
+ - Remove a few obsolete items
+ - Add items added lately to libsdl1.2, such as libts (touch screen)

+ - Change "XC-Package-Type: udeb" to "Package-Type"
+ * debian/compat: set level 9
+ * debian/source/format: Set to "3.0 (quilt)"
+ - Remove README.source, not needed with new format
+ * debian/sdl2-config.1: Fix typo, "progams"->"programs"
+ * debian/libsdl2-dev.install:
+ - Remove "usr/lib/*/*.la", discouraged
+ - Add man pages: "usr/share/man/man3/*"
+ * debian/libsdl2-dev.manpages: add file to install local "sdl2-config.1"
+ * debian/sources: Removed, possible obsolete file from long ago?
+ * debian/copyright:
+ - Upstream updated to zlib/libpng
+ - Copyright-file format conversion to 1.0
+ - Complete revamp and detailed research about copyright and licenses used,
+ it's very messy but hopefully complete

+.TH sdl2-config 1 "2012-02-20" "SDL 2.0"
+.SH NAME
+sdl2-config \- script to get information about the installed version of SDL
+.SH SYNOPSIS
+.B sdl2-config
+[ --prefix=
+.IR DIR ]
+[ --exec-prefix=
+.IR DIR ]
+[ --version ] [ --libs | --library-libs | --plugin-libs ] [ --cflags ]
+.SH DESCRIPTION
+.B sdl2-config
+is a tool that is used to configure and determine the compiler and linker
+flags that should be used to compile and link programs, libraries, and
+plugins that use SDL. It is also used internally by the m4 macros that are
+included with SDL.
+.SH OPTIONS
+.TP
+.B --cflags
+Print the compiler flags that are necessary to compile a program or library
+that uses SDL.
+.TP
+.BI --exec-prefix= DIR
+If specified, use
+.I DIR
+instead of the installation exec prefix that SDL was build with when
+computing the output for the --cflags, --libs, --library-libs, and
+--plugin-libs options. This option must be specified before any of the
+--cflags, --libs, --library-libs, and --plugin-libs options.
+.TP
+.B --libs
+Print the linker flags that are necessary to link a program that uses SDL.
+.TP
+.B --static-libs
+Print the linker flags that are necessary to statically link a program that uses SDL.
+.TP
+.B --library-libs
+Print the linker flags that are necessary to link a library that uses SDL.
+(This excludes any static objects required for linking, since these must be
+linked only by executable programs.)
+.TP
+.B --plugin-libs
+Print the linker flags that are necessary to link an SDL-using object that
+is to be accessed via
+.IR dlopen (3).
+This may include static objects with PIC symbol information. This option
+should
+.B not
+be used for ordinary shared libraries or standalone applications.
+.TP
+.BI --prefix= DIR
+If specified, use PREFIX instead of the installation prefix that SDL was
+built with when computing the output for the --cflags, --libs,
+--library-libs, and --plugin-libs options. This option is also used for
+the exec prefix if --exec-prefix was not specified. This option must be
+specified before any of the --cflags, --libs, --library-libs, and
+--plugin-libs options.
+.TP
+.B --version
+Prints the currently installed version of SDL on standard output.
+.SH EXAMPLES
+.TP
+gcc -o main.o $(sdl2-config --cflags) main.c
+is how you might use
+.B sdl2-config
+to compile a C source file for an executable program.
+.TP
+gcc -o my_app $(sdl2-config --libs) main.o util.o
+is how you might use
+.B sdl2-config
+to link compiled objects into an executable program.
+.TP
+gcc -o libSDL_nifty-2.0.so.0.0.1 $(sdl --library-libs) read.o write.o munge.o
+is how you might use
+.B sdl2-config
+to link compiled objects into a shared library.
+.TP
+gcc -o libnifty_xmms.so $(sdl --plugin-libs) stream.o blit.o deinterlace.o
+is how you might use
+.B sdl2-config
+to link compiled objects into a plugin for use by another program.

+ *
+ * This is the Simple DirectMedia Layer, a general API that provides low
+ * level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL,
+ * and 2D framebuffer across multiple platforms.
+ *
+ * SDL is written in C, but works with C++ natively, and has bindings to
+ * several other languages, including Ada, C#, Eiffel, Erlang, Euphoria,
+ * Guile, Haskell, Java, Lisp, Lua, ML, Objective C, Pascal, Perl, PHP,
+ * Pike, Pliant, Python, Ruby, and Smalltalk.
+ *
+ * This library is distributed under the zlib license, which can be
+ * found in the file "COPYING". This license allows you to use SDL
+ * freely for any purpose as long as you retain the copyright notice.
+ *
+ * The best way to learn how to use SDL is to check out the header files in
+ * the "include" subdirectory and the programs in the "test" subdirectory.
+ * The header files and test programs are well commented and always up to date.
+ * More documentation and FAQs are available online at:
+ * http://wiki.libsdl.org/
+ *
+ * If you need help with the library, or just want to discuss SDL related
+ * issues, you can join the developers mailing list:
+ * http://www.libsdl.org/mailing-list.php
+ *
+ * Enjoy!

+ * \file SDL_haptic.h
+ *
+ * \brief The SDL Haptic subsystem allows you to control haptic (force feedback)
+ * devices.
+ *
+ * The basic usage is as follows:
+ * - Initialize the Subsystem (::SDL_INIT_HAPTIC).
+ * - Open a Haptic Device.
+ * - SDL_HapticOpen() to open from index.
+ * - SDL_HapticOpenFromJoystick() to open from an existing joystick.
+ * - Create an effect (::SDL_HapticEffect).
+ * - Upload the effect with SDL_HapticNewEffect().
+ * - Run the effect with SDL_HapticRunEffect().
+ * - (optional) Free the effect with SDL_HapticDestroyEffect().
+ * - Close the haptic device with SDL_HapticClose().
+ *
+ * \par Simple rumble example:
+ * \code
+ * SDL_Haptic *haptic;
+ *
+ * // Open the device
+ * haptic = SDL_HapticOpen( 0 );
+ * if (haptic == NULL)
+ * return -1;
+ *
+ * // Initialize simple rumble
+ * if (SDL_HapticRumbleInit( haptic ) != 0)
+ * return -1;
+ *
+ * // Play effect at 50% strength for 2 seconds
+ * if (SDL_HapticRumblePlay( haptic, 0.5, 2000 ) != 0)
+ * return -1;
+ * SDL_Delay( 2000 );
+ *
+ * // Clean up
+ * SDL_HapticClose( haptic );
+ * \endcode
+ *
+ * \par Complete example:
+ * \code
+ * int test_haptic( SDL_Joystick * joystick ) {
+ * SDL_Haptic *haptic;
+ * SDL_HapticEffect effect;
+ * int effect_id;
+ *
+ * // Open the device
+ * haptic = SDL_HapticOpenFromJoystick( joystick );
+ * if (haptic == NULL) return -1; // Most likely joystick isn't haptic
+ *
+ * // See if it can do sine waves
+ * if ((SDL_HapticQuery(haptic) & SDL_HAPTIC_SINE)==0) {
+ * SDL_HapticClose(haptic); // No sine effect
+ * return -1;
+ * }
+ *
+ * // Create the effect
+ * memset( &effect, 0, sizeof(SDL_HapticEffect) ); // 0 is safe default
+ * effect.type = SDL_HAPTIC_SINE;
+ * effect.periodic.direction.type = SDL_HAPTIC_POLAR; // Polar coordinates
+ * effect.periodic.direction.dir[0] = 18000; // Force comes from south
+ * effect.periodic.period = 1000; // 1000 ms
+ * effect.periodic.magnitude = 20000; // 20000/32767 strength
+ * effect.periodic.length = 5000; // 5 seconds long
+ * effect.periodic.attack_length = 1000; // Takes 1 second to get max strength
+ * effect.periodic.fade_length = 1000; // Takes 1 second to fade away
+ *
+ * // Upload the effect
+ * effect_id = SDL_HapticNewEffect( haptic, &effect );
+ *
+ * // Test the effect
+ * SDL_HapticRunEffect( haptic, effect_id, 1 );
+ * SDL_Delay( 5000); // Wait for the effect to finish
+ *
+ * // We destroy the effect, although closing the device also does this
+ * SDL_HapticDestroyEffect( haptic, effect_id );
+ *
+ * // Close the device
+ * SDL_HapticClose(haptic);
+ *
+ * return 0; // Success
+ * }
+ * \endcode
+ *

+ *
+ * If type is ::SDL_HAPTIC_POLAR, direction is encoded by hundredths of a
+ * degree starting north and turning clockwise. ::SDL_HAPTIC_POLAR only uses
+ * the first \c dir parameter. The cardinal directions would be:
+ * - North: 0 (0 degrees)
+ * - East: 9000 (90 degrees)
+ * - South: 18000 (180 degrees)
+ * - West: 27000 (270 degrees)
+ *
+ * If type is ::SDL_HAPTIC_CARTESIAN, direction is encoded by three positions
+ * (X axis, Y axis and Z axis (with 3 axes)). ::SDL_HAPTIC_CARTESIAN uses
+ * the first three \c dir parameters. The cardinal directions would be:
+ * - North: 0,-1, 0
+ * - East: -1, 0, 0
+ * - South: 0, 1, 0
+ * - West: 1, 0, 0
+ *
+ * The Z axis represents the height of the effect if supported, otherwise
+ * it's unused. In cartesian encoding (1, 2) would be the same as (2, 4), you
+ * can use any multiple you want, only the direction matters.
+ *
+ * If type is ::SDL_HAPTIC_SPHERICAL, direction is encoded by two rotations.
+ * The first two \c dir parameters are used. The \c dir parameters are as
+ * follows (all values are in hundredths of degrees):
+ * - Degrees from (1, 0) rotated towards (0, 1).
+ * - Degrees towards (0, 0, 1) (device needs at least 3 axes).
+ *
+ *
+ * Example of force coming from the south with all encodings (force coming

+ * // Cartesian directions
+ * direction.type = SDL_HAPTIC_CARTESIAN; // Using cartesian direction encoding.
+ * direction.dir[0] = 0; // X position
+ * direction.dir[1] = 1; // Y position
+ * // Assuming the device has 2 axes, we don't need to specify third parameter.
+ *
+ * // Polar directions
+ * direction.type = SDL_HAPTIC_POLAR; // We'll be using polar direction encoding.
+ * direction.dir[0] = 18000; // Polar only uses first parameter
+ *
+ * // Spherical coordinates

+ If any of the operations are not provided then we must emulate some
+ of them. That means we need a nice implementation of spin locks
+ that avoids the "one big lock" problem. We use a vector of spin
+ locks and pick which one to use based on the address of the operand
+ of the function.
+
+ To generate the index of the lock we first shift by 3 bits to get
+ rid on the zero bits that result from 32 and 64 bit allignment of
+ data. We then mask off all but 5 bits and use those 5 bits as an
+ index into the table.
+
+ Picking the lock this way insures that accesses to the same data at
+ the same time will go to the same lock. OTOH, accesses to different
+ data have only a 1/32 chance of hitting the same lock. That should
+ pretty much eliminate the chances of several atomic operations on
+ different data from waiting on the same "big lock". If it isn't
+ then the table of locks can be expanded to a new size so long as
+ the new size is a power of two.

+ *
+ * 2. Approximation of log(1+f).

+ * = 2s + 2/3 s**3 + 2/5 s**5 + .....,
+ * = 2s + s*R
+ * We use a special Reme algorithm on [0,0.1716] to generate
+ * a polynomial of degree 14 to approximate R The maximum error
+ * of this polynomial approximation is bounded by 2**-58.45. In
+ * other words,
+ * 2 4 6 8 10 12 14

+ * | Lg1*s +...+Lg7*s - R(z) | <= 2
+ * | |
+ * Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.
+ * In order to guarantee error in log below 1ulp, we compute log
+ * by
+ * log(1+f) = f - s*(f - R) (if f is not too large)
+ * log(1+f) = f - (hfsq - s*(hfsq+R)). (better accuracy)
+ *
+ * 3. Finally, log(x) = k*ln2 + log(1+f).
+ * = k*ln2_hi+(f-(hfsq-(s*(hfsq+R)+k*ln2_lo)))
+ * Here ln2 is split into two floating point number:
+ * ln2_hi + ln2_lo,
+ * where n*ln2_hi is always exact for |n| < 2000.
+ *
+ * Special cases:
+ * log(x) is NaN with signal if x < 0 (including -INF) ;
+ * log(+INF) is +INF; log(0) is -INF with signal;
+ * log(NaN) is that NaN with no signal.
+ *
+ * Accuracy:
+ * according to an error analysis, the error is always less than
+ * 1 ulp (unit in the last place).
+ *

+ * where w1 has 53-24 = 29 bit trailing zeros.
+ * 2. Perform y*log2(x) = n+y' by simulating muti-precision
+ * arithmetic, where |y'|<=0.5.
+ * 3. Return x**y = 2**n*exp(y'*log2)
+ *
+ * Special cases:
+ * 1. (anything) ** 0 is 1
+ * 2. (anything) ** 1 is itself
+ * 3. (anything) ** NAN is NAN
+ * 4. NAN ** (anything except 0) is NAN
+ * 5. +-(|x| > 1) ** +INF is +INF
+ * 6. +-(|x| > 1) ** -INF is +0
+ * 7. +-(|x| < 1) ** +INF is +0
+ * 8. +-(|x| < 1) ** -INF is +INF
+ * 9. +-1 ** +-INF is NAN
+ * 10. +0 ** (+anything except 0, NAN) is +0
+ * 11. -0 ** (+anything except 0, NAN, odd integer) is +0
+ * 12. +0 ** (-anything except 0, NAN) is +INF

+ * 15. +INF ** (+anything except 0,NAN) is +INF
+ * 16. +INF ** (-anything except 0,NAN) is +0
+ * 17. -INF ** (anything) = -0 ** (-anything)
+ * 18. (-anything) ** (integer) is (-1)**(integer)*(+anything**integer)
+ * 19. (-anything except 0 and inf) ** (non-integer) is NAN
+ *
+ * Accuracy:
+ * pow(x,y) returns x**y nearly rounded. In particular
+ * pow(integer,integer)
+ * always returns the correct integer provided it is
+ * representable.
+ *
+ * Constants :
+ * The hexadecimal values are the intended ones for the following
+ * constants. The decimal values may be used, provided that the
+ * compiler will convert from decimal to binary accurately enough
+ * to produce the hexadecimal values shown.

+ * Return correctly rounded sqrt.
+ * ------------------------------------------
+ * | Use the hardware sqrt if you have one |
+ * ------------------------------------------
+ * Method:
+ * Bit by bit method using integer arithmetic. (Slow, but portable)
+ * 1. Normalization
+ * Scale x to y in [1,4) with even powers of 2:
+ * find an integer k such that 1 <= (y=x*2^(2k)) < 4, then
+ * sqrt(x) = 2^k * sqrt(y)
+ * 2. Bit by bit computation
+ * Let q = sqrt(y) truncated to i bit after binary point (q = 1),
+ * i 0
+ * i+1 2
+ * s = 2*q , and y = 2 * ( y - q ). (1)
+ * i i i i
+ *
+ * To compute q from q , one checks whether
+ * i+1 i
+ *
+ * -(i+1) 2
+ * (q + 2 ) <= y. (2)
+ * i
+ * -(i+1)
+ * If (2) is false, then q = q ; otherwise q = q + 2 .
+ * i+1 i i+1 i
+ *
+ * With some algebric manipulation, it is not difficult to see
+ * that (2) is equivalent to
+ * -(i+1)
+ * s + 2 <= y (3)
+ * i i
+ *
+ * The advantage of (3) is that s and y can be computed by
+ * i i
+ * the following recurrence formula:
+ * if (3) is false
+ *
+ * s = s , y = y ; (4)
+ * i+1 i i+1 i
+ *
+ * otherwise,
+ * -i -(i+1)
+ * s = s + 2 , y = y - s - 2 (5)
+ * i+1 i i+1 i i
+ *
+ * One may easily use induction to prove (4) and (5).
+ * Note. Since the left hand side of (3) contain only i+2 bits,
+ * it does not necessary to do a full (53-bit) comparison
+ * in (3).
+ * 3. Final rounding
+ * After generating the 53 bits result, we compute one more bit.
+ * Together with the remainder, we can decide whether the
+ * result is exact, bigger than 1/2ulp, or less than 1/2ulp
+ * (it will never equal to 1/2ulp).
+ * The rounding mode can be detected by checking whether
+ * huge + tiny is equal to huge, and whether huge - tiny is
+ * equal to huge for some floating point number "huge" and "tiny".
+ *
+ * Special cases:
+ * sqrt(+-0) = +-0 ... exact
+ * sqrt(inf) = inf
+ * sqrt(-ve) = NaN ... with invalid signal
+ * sqrt(NaN) = NaN ... with invalid signal for signaling NaN
+ *
+ * Other methods : see the appended file at the end of the program below.

+Other methods (use floating-point arithmetic)
+-------------
+(This is a copy of a drafted paper by Prof W. Kahan
+and K.C. Ng, written in May, 1986)
+
+ Two algorithms are given here to implement sqrt(x)
+ (IEEE double precision arithmetic) in software.
+ Both supply sqrt(x) correctly rounded. The first algorithm (in
+ Section A) uses newton iterations and involves four divisions.
+ The second one uses reciproot iterations to avoid division, but
+ requires more multiplications. Both algorithms need the ability
+ to chop results of arithmetic operations instead of round them,
+ and the INEXACT flag to indicate when an arithmetic operation
+ is executed exactly with no roundoff error, all part of the
+ standard (IEEE 754-1985). The ability to perform shift, add,
+ subtract and logical AND operations upon 32-bit words is needed
+ too, though not part of the standard.
+
+A. sqrt(x) by Newton Iteration
+
+ (1) Initial approximation
+
+ Let x0 and x1 be the leading and the trailing 32-bit words of
+ a floating point number x (in IEEE double format) respectively
+
+ 1 11 52 ...widths
+ ------------------------------------------------------
+ x: |s| e | f |
+ ------------------------------------------------------
+ msb lsb msb lsb ...order
+
+
+ ------------------------ ------------------------
+ x0: |s| e | f1 | x1: | f2 |
+ ------------------------ ------------------------
+
+ By performing shifts and subtracts on x0 and x1 (both regarded
+ as integers), we obtain an 8-bit approximation of sqrt(x) as
+ follows.
+
+ k := (x0>>1) + 0x1ff80000;
+ y0 := k - T1[31&(k>>15)]. ... y ~ sqrt(x) to 8 bits
+ Here k is a 32-bit integer and T1[] is an integer array containing
+ correction terms. Now magically the floating value of y (y's
+ leading 32-bit word is y0, the value of its trailing word is 0)
+ approximates sqrt(x) to almost 8-bit.
+
+ Value of T1:
+ static int T1[32]= {
+ 0, 1024, 3062, 5746, 9193, 13348, 18162, 23592,
+ 29598, 36145, 43202, 50740, 58733, 67158, 75992, 85215,
+ 83599, 71378, 60428, 50647, 41945, 34246, 27478, 21581,
+ 16499, 12183, 8588, 5674, 3403, 1742, 661, 130,};
+
+ (2) Iterative refinement
+
+ Apply Heron's rule three times to y, we have y approximates
+ sqrt(x) to within 1 ulp (Unit in the Last Place):
+
+ y := (y+x/y)/2 ... almost 17 sig. bits
+ y := (y+x/y)/2 ... almost 35 sig. bits
+ y := y-(y-x/y)/2 ... within 1 ulp
+
+
+ Remark 1.
+ Another way to improve y to within 1 ulp is:
+
+ y := (y+x/y) ... almost 17 sig. bits to 2*sqrt(x)
+ y := y - 0x00100006 ... almost 18 sig. bits to sqrt(x)
+
+ 2
+ (x-y )*y
+ y := y + 2* ---------- ...within 1 ulp
+ 2
+ 3y + x
+
+
+ This formula has one division fewer than the one above; however,
+ it requires more multiplications and additions. Also x must be
+ scaled in advance to avoid spurious overflow in evaluating the
+ expression 3y*y+x. Hence it is not recommended uless division
+ is slow. If division is very slow, then one should use the
+ reciproot algorithm given in section B.
+
+ (3) Final adjustment
+
+ By twiddling y's last bit it is possible to force y to be
+ correctly rounded according to the prevailing rounding mode
+ as follows. Let r and i be copies of the rounding mode and
+ inexact flag before entering the square root program. Also we
+ use the expression y+-ulp for the next representable floating
+ numbers (up and down) of y. Note that y+-ulp = either fixed
+ point y+-1, or multiply y by nextafter(1,+-inf) in chopped
+ mode.
+
+ I := FALSE; ... reset INEXACT flag I
+ R := RZ; ... set rounding mode to round-toward-zero
+ z := x/y; ... chopped quotient, possibly inexact
+ If(not I) then { ... if the quotient is exact
+ if(z=y) {
+ I := i; ... restore inexact flag
+ R := r; ... restore rounded mode
+ return sqrt(x):=y.
+ } else {
+ z := z - ulp; ... special rounding
+ }
+ }
+ i := TRUE; ... sqrt(x) is inexact
+ If (r=RN) then z=z+ulp ... rounded-to-nearest
+ If (r=RP) then { ... round-toward-+inf
+ y = y+ulp; z=z+ulp;
+ }
+ y := y+z; ... chopped sum
+ y0:=y0-0x00100000; ... y := y/2 is correctly rounded.
+ I := i; ... restore inexact flag
+ R := r; ... restore rounded mode
+ return sqrt(x):=y.
+
+ (4) Special cases
+
+ Square root of +inf, +-0, or NaN is itself;
+ Square root of a negative number is NaN with invalid signal.
+
+
+B. sqrt(x) by Reciproot Iteration
+
+ (1) Initial approximation
+
+ Let x0 and x1 be the leading and the trailing 32-bit words of
+ a floating point number x (in IEEE double format) respectively
+ (see section A). By performing shifs and subtracts on x0 and y0,
+ we obtain a 7.8-bit approximation of 1/sqrt(x) as follows.
+
+ k := 0x5fe80000 - (x0>>1);
+ y0:= k - T2[63&(k>>14)]. ... y ~ 1/sqrt(x) to 7.8 bits
+
+ Here k is a 32-bit integer and T2[] is an integer array
+ containing correction terms. Now magically the floating
+ value of y (y's leading 32-bit word is y0, the value of
+ its trailing word y1 is set to zero) approximates 1/sqrt(x)
+ to almost 7.8-bit.
+

+
+ (2) Iterative refinement
+
+ Apply Reciproot iteration three times to y and multiply the
+ result by x to get an approximation z that matches sqrt(x)
+ to about 1 ulp. To be exact, we will have
+ -1ulp < sqrt(x)-z<1.0625ulp.
+
+ ... set rounding mode to Round-to-nearest
+ y := y*(1.5-0.5*x*y*y) ... almost 15 sig. bits to 1/sqrt(x)
+ y := y*((1.5-2^-30)+0.5*x*y*y)... about 29 sig. bits to 1/sqrt(x)
+ ... special arrangement for better accuracy
+ z := x*y ... 29 bits to sqrt(x), with z*y<1
+ z := z + 0.5*z*(1-z*y) ... about 1 ulp to sqrt(x)
+
+ Remark 2. The constant 1.5-2^-30 is chosen to bias the error so that
+ (a) the term z*y in the final iteration is always less than 1;
+ (b) the error in the final result is biased upward so that
+ -1 ulp < sqrt(x) - z < 1.0625 ulp
+ instead of |sqrt(x)-z|<1.03125ulp.
+
+ (3) Final adjustment
+
+ By twiddling y's last bit it is possible to force y to be
+ correctly rounded according to the prevailing rounding mode
+ as follows. Let r and i be copies of the rounding mode and
+ inexact flag before entering the square root program. Also we
+ use the expression y+-ulp for the next representable floating
+ numbers (up and down) of y. Note that y+-ulp = either fixed
+ point y+-1, or multiply y by nextafter(1,+-inf) in chopped
+ mode.
+
+ R := RZ; ... set rounding mode to round-toward-zero
+ switch(r) {
+ case RN: ... round-to-nearest
+ if(x<= z*(z-ulp)...chopped) z = z - ulp; else
+ if(x<= z*(z+ulp)...chopped) z = z; else z = z+ulp;
+ break;
+ case RZ:case RM: ... round-to-zero or round-to--inf
+ R:=RP; ... reset rounding mod to round-to-+inf
+ if(x<z*z ... rounded up) z = z - ulp; else
+ if(x>=(z+ulp)*(z+ulp) ...rounded up) z = z+ulp;
+ break;
+ case RP: ... round-to-+inf
+ if(x>(z+ulp)*(z+ulp)...chopped) z = z+2*ulp; else
+ if(x>z*z ...chopped) z = z+ulp;
+ break;
+ }
+
+ Remark 3. The above comparisons can be done in fixed point. For
+ example, to compare x and w=z*z chopped, it suffices to compare
+ x1 and w1 (the trailing parts of x and w), regarding them as
+ two's complement integers.
+
+ ...Is z an exact square root?
+ To determine whether z is an exact square root of x, let z1 be the
+ trailing part of z, and also let x0 and x1 be the leading and
+ trailing parts of x.
+
+ If ((z1&0x03ffffff)!=0) ... not exact if trailing 26 bits of z!=0
+ I := 1; ... Raise Inexact flag: z is not exact
+ else {
+ j := 1 - [(x0>>20)&1] ... j = logb(x) mod 2
+ k := z1 >> 26; ... get z's 25-th and 26-th
+ fraction bits
+ I := i or (k&j) or ((k&(j+j+1))!=(x1&3));
+ }
+ R:= r ... restore rounded mode
+ return sqrt(x):=z.
+
+ If multiplication is cheaper then the foregoing red tape, the
+ Inexact flag can be evaluated by
+
+ I := i;
+ I := (z*z!=x) or I.
+
+ Note that z*z can overwrite I; this value must be sensed if it is
+ True.
+
+ Remark 4. If z*z = x exactly, then bit 25 to bit 0 of z1 must be
+ zero.
+
+ --------------------
+ z1: | f2 |
+ --------------------
+ bit 31 bit 0
+
+ Further more, bit 27 and 26 of z1, bit 0 and 1 of x1, and the odd
+ or even of logb(x) have the following relations:
+
+ -------------------------------------------------
+ bit 27,26 of z1 bit 1,0 of x1 logb(x)
+ -------------------------------------------------
+ 00 00 odd and even
+ 01 01 even
+ 10 10 odd
+ 10 00 even
+ 11 01 even
+ -------------------------------------------------

+ (4) Special cases (see (4) of Section A).

+ *
+ * (2/pi) is represented by an array of 24-bit integers in ipio2[].
+ *
+ * Input parameters:
+ * x[] The input value (must be positive) is broken into nx
+ * pieces of 24-bit integers in double precision format.
+ * x[i] will be the i-th 24 bit of x. The scaled exponent
+ * of x[0] is given in input parameter e0 (i.e., x[0]*2^e0
+ * match x's up to 24 bits.
+ *
+ * Example of breaking a double positive z into x[0]+x[1]+x[2]:
+ * e0 = ilogb(z)-23
+ * z = scalbn(z,-e0)
+ * for i = 0,1,2
+ * x[i] = floor(z)
+ * z = (z-x[i])*2**24
+ *
+ *
+ * y[] ouput result in an array of double precision numbers.
+ * The dimension of y[] is:
+ * 24-bit precision 1
+ * 53-bit precision 2
+ * 64-bit precision 2
+ * 113-bit precision 3
+ * The actual value is the sum of them. Thus for 113-bit
+ * precison, one may have to do something like:
+ *
+ * long double t,w,r_head, r_tail;
+ * t = (long double)y[2] + (long double)y[1];
+ * w = (long double)y[0];
+ * r_head = t+w;
+ * r_tail = w - (r_head - t);
+ *
+ * e0 The exponent of x[0]
+ *
+ * nx dimension of x[]
+ *
+ * prec an integer indicating the precision:
+ * 0 24 bits (single)
+ * 1 53 bits (double)
+ * 2 64 bits (extended)
+ * 3 113 bits (quad)
+ *
+ * ipio2[]
+ * integer array, contains the (24*i)-th to (24*i+23)-th
+ * bit of 2/pi after binary point. The corresponding
+ * floating value is
+ *
+ * ipio2[i] * 2^(-24(i+1)).
+ *
+ * External function:
+ * double scalbn(), floor();
+ *
+ *
+ * Here is the description of some local variables:
+ *
+ * jk jk+1 is the initial number of terms of ipio2[] needed
+ * in the computation. The recommended value is 2,3,4,
+ * 6 for single, double, extended,and quad.
+ *
+ * jz local integer variable indicating the number of
+ * terms of ipio2[] used.
+ *
+ * jx nx - 1
+ *
+ * jv index for pointing to the suitable ipio2[] for the
+ * computation. In general, we want
+ * ( 2^e0*x[0] * ipio2[jv-1]*2^(-24jv) )/8
+ * is an integer. Thus
+ * e0-3-24*jv >= 0 or (e0-3)/24 >= jv
+ * Hence jv = max(0,(e0-3)/24).
+ *
+ * jp jp+1 is the number of terms in PIo2[] needed, jp = jk.
+ *
+ * q[] double array with integral value, representing the
+ * 24-bits chunk of the product of x and 2/pi.
+ *
+ * q0 the corresponding exponent of q[0]. Note that the
+ * exponent for q[i] would be q0-24*i.
+ *
+ * PIo2[] double precision array, obtained by cutting pi/2
+ * into 24 bits chunks.
+ *
+ * f[] ipio2[] in floating point
+ *
+ * iq[] integer array by breaking up q[] in 24-bits chunk.
+ *
+ * fq[] final product of x*(2/pi) in fq[0],..,fq[jk]

+ This MMX assembler is my first assembler/MMX program ever.

+ Send patches to:

+
+ After it worked fine I have "obfuscated" the code a bit to have
+ more parallism in the MMX units. This means I moved
+ initilisation around and delayed other instruction.
+ Performance measurement did not show that this brought any advantage
+ but in theory it _should_ be faster this way.
+
+ The overall performanve gain to the C based dither was 30%-40%.
+ The MMX routine calculates 256bit=8RGB values in each cycle
+ (4 for row1 & 4 for row2)
+
+ The red/green/blue.. coefficents are taken from the mpeg_play
+ player. They look nice, but I dont know if you can have
+ better values, to avoid integer rounding errors.

+ MultiMedia eXtensions GCC interface library for IA32.
+
+ To use this library, simply include this header file

+ simply using -O on the GCC command line.
+
+ Compiling with -DMMX_TRACE will cause detailed trace
+ output to be sent to stderr for each mmx operation.
+ This adds lots of code, and obviously slows execution to
+ a crawl, but can be very useful for debugging.

+ This is a version (aka dlmalloc) of malloc/free/realloc written by

+ http://creativecommons.org/licenses/publicdomain. Send questions,
+ comments, complaints, performance data, etc to dl@cs.oswego.edu
+
+* Version 2.8.3 Thu Sep 22 11:16:15 2005 Doug Lea (dl at gee)
+
+ Note: There may be an updated version of this malloc obtainable at
+ ftp://gee.cs.oswego.edu/pub/misc/malloc.c
+ Check before installing!
+
+* Quickstart
+
+ This library is all in one file to simplify the most common usage:
+ ftp it, compile it (-O3), and link it into another program. All of
+ the compile-time options default to reasonable values for use on
+ most platforms. You might later want to step through various
+ compile-time and dynamic tuning options.
+
+ For convenience, an include file for code using this malloc is at:
+ ftp://gee.cs.oswego.edu/pub/misc/malloc-2.8.3.h
+ You don't really need this .h file unless you call functions not
+ defined in your system include files. The .h file contains only the
+ excerpts from this file needed for using this malloc on ANSI C/C++
+ systems, so long as you haven't changed compile-time options about
+ naming and tuning parameters. If you do, then you can create your
+ own malloc.h that does include all settings by cutting at the point
+ indicated below. Note that you may already by default be using a C
+ library containing a malloc that is based on some version of this
+ malloc (for example in linux). You might still want to use the one
+ in this file to customize settings or to avoid overheads associated
+ with library versions.
+
+* Vital statistics:
+
+ Supported pointer/size_t representation: 4 or 8 bytes
+ size_t MUST be an unsigned type of the same width as
+ pointers. (If you are using an ancient system that declares
+ size_t as a signed type, or need it to be a different width
+ than pointers, you can use a previous release of this malloc
+ (e.g. 2.7.2) supporting these.)
+
+ Alignment: 8 bytes (default)
+ This suffices for nearly all current machines and C compilers.
+ However, you can define MALLOC_ALIGNMENT to be wider than this
+ if necessary (up to 128bytes), at the expense of using more space.
+
+ Minimum overhead per allocated chunk: 4 or 8 bytes (if 4byte sizes)
+ 8 or 16 bytes (if 8byte sizes)
+ Each malloced chunk has a hidden word of overhead holding size
+ and status information, and additional cross-check word
+ if FOOTERS is defined.
+
+ Minimum allocated size: 4-byte ptrs: 16 bytes (including overhead)
+ 8-byte ptrs: 32 bytes (including overhead)
+
+ Even a request for zero bytes (i.e., malloc(0)) returns a
+ pointer to something of the minimum allocatable size.
+ The maximum overhead wastage (i.e., number of extra bytes
+ allocated than were requested in malloc) is less than or equal
+ to the minimum size, except for requests >= mmap_threshold that
+ are serviced via mmap(), where the worst case wastage is about
+ 32 bytes plus the remainder from a system page (the minimal
+ mmap unit); typically 4096 or 8192 bytes.
+
+ Security: static-safe; optionally more or less
+ The "security" of malloc refers to the ability of malicious
+ code to accentuate the effects of errors (for example, freeing
+ space that is not currently malloc'ed or overwriting past the
+ ends of chunks) in code that calls malloc. This malloc
+ guarantees not to modify any memory locations below the base of
+ heap, i.e., static variables, even in the presence of usage
+ errors. The routines additionally detect most improper frees
+ and reallocs. All this holds as long as the static bookkeeping
+ for malloc itself is not corrupted by some other means. This
+ is only one aspect of security -- these checks do not, and
+ cannot, detect all possible programming errors.
+
+ If FOOTERS is defined nonzero, then each allocated chunk
+ carries an additional check word to verify that it was malloced
+ from its space. These check words are the same within each
+ execution of a program using malloc, but differ across
+ executions, so externally crafted fake chunks cannot be
+ freed. This improves security by rejecting frees/reallocs that
+ could corrupt heap memory, in addition to the checks preventing
+ writes to statics that are always on. This may further improve
+ security at the expense of time and space overhead. (Note that
+ FOOTERS may also be worth using with MSPACES.)
+
+ By default detected errors cause the program to abort (calling
+ "abort()"). You can override this to instead proceed past
+ errors by defining PROCEED_ON_ERROR. In this case, a bad free
+ has no effect, and a malloc that encounters a bad address
+ caused by user overwrites will ignore the bad address by
+ dropping pointers and indices to all known memory. This may
+ be appropriate for programs that should continue if at all
+ possible in the face of programming errors, although they may
+ run out of memory because dropped memory is never reclaimed.
+
+ If you don't like either of these options, you can define
+ CORRUPTION_ERROR_ACTION and USAGE_ERROR_ACTION to do anything
+ else. And if if you are sure that your program using malloc has
+ no errors or vulnerabilities, you can define INSECURE to 1,
+ which might (or might not) provide a small performance improvement.
+
+ Thread-safety: NOT thread-safe unless USE_LOCKS defined
+ When USE_LOCKS is defined, each public call to malloc, free,
+ etc is surrounded with either a pthread mutex or a win32
+ spinlock (depending on WIN32). This is not especially fast, and
+ can be a major bottleneck. It is designed only to provide
+ minimal protection in concurrent environments, and to provide a
+ basis for extensions. If you are using malloc in a concurrent
+ program, consider instead using ptmalloc, which is derived from
+ a version of this malloc. (See http://www.malloc.de).
+
+ System requirements: Any combination of MORECORE and/or MMAP/MUNMAP
+ This malloc can use unix sbrk or any emulation (invoked using
+ the CALL_MORECORE macro) and/or mmap/munmap or any emulation
+ (invoked using CALL_MMAP/CALL_MUNMAP) to get and release system
+ memory. On most unix systems, it tends to work best if both
+ MORECORE and MMAP are enabled. On Win32, it uses emulations
+ based on VirtualAlloc. It also uses common C library functions
+ like memset.
+
+ Compliance: I believe it is compliant with the Single Unix Specification
+ (See http://www.unix.org). Also SVID/XPG, ANSI C, and probably
+ others as well.
+
+* Overview of algorithms
+
+ This is not the fastest, most space-conserving, most portable, or
+ most tunable malloc ever written. However it is among the fastest
+ while also being among the most space-conserving, portable and
+ tunable. Consistent balance across these factors results in a good
+ general-purpose allocator for malloc-intensive programs.
+
+ In most ways, this malloc is a best-fit allocator. Generally, it
+ chooses the best-fitting existing chunk for a request, with ties
+ broken in approximately least-recently-used order. (This strategy
+ normally maintains low fragmentation.) However, for requests less
+ than 256bytes, it deviates from best-fit when there is not an
+ exactly fitting available chunk by preferring to use space adjacent
+ to that used for the previous small request, as well as by breaking
+ ties in approximately most-recently-used order. (These enhance
+ locality of series of small allocations.) And for very large requests
+ (>= 256Kb by default), it relies on system memory mapping
+ facilities, if supported. (This helps avoid carrying around and
+ possibly fragmenting memory used only for large chunks.)
+
+ All operations (except malloc_stats and mallinfo) have execution
+ times that are bounded by a constant factor of the number of bits in
+ a size_t, not counting any clearing in calloc or copying in realloc,
+ or actions surrounding MORECORE and MMAP that have times
+ proportional to the number of non-contiguous regions returned by
+ system allocation routines, which is often just 1.
+
+ The implementation is not very modular and seriously overuses
+ macros. Perhaps someday all C compilers will do as good a job
+ inlining modular code as can now be done by brute-force expansion,
+ but now, enough of them seem not to.
+
+ Some compilers issue a lot of warnings about code that is
+ dead/unreachable only on some platforms, and also about intentional
+ uses of negation on unsigned types. All known cases of each can be
+ ignored.
+
+ For a longer but out of date high-level description, see
+ http://gee.cs.oswego.edu/dl/html/malloc.html
+
+* MSPACES
+ If MSPACES is defined, then in addition to malloc, free, etc.,
+ this file also defines mspace_malloc, mspace_free, etc. These
+ are versions of malloc routines that take an "mspace" argument
+ obtained using create_mspace, to control all internal bookkeeping.
+ If ONLY_MSPACES is defined, only these versions are compiled.
+ So if you would like to use this allocator for only some allocations,
+ and your system malloc for others, you can compile with
+ ONLY_MSPACES and then do something like...
+ static mspace mymspace = create_mspace(0,0); // for example
+ #define mymalloc(bytes) mspace_malloc(mymspace, bytes)
+
+ (Note: If you only need one instance of an mspace, you can instead
+ use "USE_DL_PREFIX" to relabel the global malloc.)
+
+ You can similarly create thread-local allocators by storing
+ mspaces as thread-locals. For example:
+ static __thread mspace tlms = 0;
+ void* tlmalloc(size_t bytes) {
+ if (tlms == 0) tlms = create_mspace(0, 0);
+ return mspace_malloc(tlms, bytes);
+ }
+ void tlfree(void* mem) { mspace_free(tlms, mem); }
+
+ Unless FOOTERS is defined, each mspace is completely independent.
+ You cannot allocate from one and free to another (although
+ conformance is only weakly checked, so usage errors are not always
+ caught). If FOOTERS is defined, then each chunk carries around a tag
+ indicating its originating mspace, and frees are directed to their
+ originating spaces.
+
+ ------------------------- Compile-time options ---------------------------
+
+Be careful in setting #define values for numerical constants of type
+size_t. On some systems, literal values are not automatically extended
+to size_t precision unless they are explicitly casted.
+
+WIN32 default: defined if _WIN32 defined
+ Defining WIN32 sets up defaults for MS environment and compilers.
+ Otherwise defaults are for unix.
+
+MALLOC_ALIGNMENT default: (size_t)8
+ Controls the minimum alignment for malloc'ed chunks. It must be a
+ power of two and at least 8, even on machines for which smaller
+ alignments would suffice. It may be defined as larger than this
+ though. Note however that code and data structures are optimized for
+ the case of 8-byte alignment.
+
+MSPACES default: 0 (false)
+ If true, compile in support for independent allocation spaces.
+ This is only supported if HAVE_MMAP is true.
+
+ONLY_MSPACES default: 0 (false)
+ If true, only compile in mspace versions, not regular versions.
+
+USE_LOCKS default: 0 (false)
+ Causes each call to each public routine to be surrounded with
+ pthread or WIN32 mutex lock/unlock. (If set true, this can be
+ overridden on a per-mspace basis for mspace versions.)
+
+FOOTERS default: 0
+ If true, provide extra checking and dispatching by placing
+ information in the footers of allocated chunks. This adds
+ space and time overhead.
+
+INSECURE default: 0
+ If true, omit checks for usage errors and heap space overwrites.
+
+USE_DL_PREFIX default: NOT defined
+ Causes compiler to prefix all public routines with the string 'dl'.
+ This can be useful when you only want to use this malloc in one part
+ of a program, using your regular system malloc elsewhere.
+
+ABORT default: defined as abort()
+ Defines how to abort on failed checks. On most systems, a failed
+ check cannot die with an "assert" or even print an informative
+ message, because the underlying print routines in turn call malloc,
+ which will fail again. Generally, the best policy is to simply call
+ abort(). It's not very useful to do more than this because many
+ errors due to overwriting will show up as address faults (null, odd
+ addresses etc) rather than malloc-triggered checks, so will also
+ abort. Also, most compilers know that abort() does not return, so
+ can better optimize code conditionally calling it.
+
+PROCEED_ON_ERROR default: defined as 0 (false)
+ Controls whether detected bad addresses cause them to bypassed
+ rather than aborting. If set, detected bad arguments to free and
+ realloc are ignored. And all bookkeeping information is zeroed out
+ upon a detected overwrite of freed heap space, thus losing the
+ ability to ever return it from malloc again, but enabling the
+ application to proceed. If PROCEED_ON_ERROR is defined, the
+ static variable malloc_corruption_error_count is compiled in
+ and can be examined to see if errors have occurred. This option
+ generates slower code than the default abort policy.
+
+DEBUG default: NOT defined
+ The DEBUG setting is mainly intended for people trying to modify
+ this code or diagnose problems when porting to new platforms.
+ However, it may also be able to better isolate user errors than just
+ using runtime checks. The assertions in the check routines spell
+ out in more detail the assumptions and invariants underlying the
+ algorithms. The checking is fairly extensive, and will slow down
+ execution noticeably. Calling malloc_stats or mallinfo with DEBUG
+ set will attempt to check every non-mmapped allocated and free chunk
+ in the course of computing the summaries.
+
+ABORT_ON_ASSERT_FAILURE default: defined as 1 (true)
+ Debugging assertion failures can be nearly impossible if your
+ version of the assert macro causes malloc to be called, which will
+ lead to a cascade of further failures, blowing the runtime stack.
+ ABORT_ON_ASSERT_FAILURE cause assertions failures to call abort(),
+ which will usually make debugging easier.
+
+MALLOC_FAILURE_ACTION default: sets errno to ENOMEM, or no-op on win32
+ The action to take before "return 0" when malloc fails to be able to
+ return memory because there is none available.
+
+HAVE_MORECORE default: 1 (true) unless win32 or ONLY_MSPACES
+ True if this system supports sbrk or an emulation of it.
+
+MORECORE default: sbrk
+ The name of the sbrk-style system routine to call to obtain more
+ memory. See below for guidance on writing custom MORECORE
+ functions. The type of the argument to sbrk/MORECORE varies across
+ systems. It cannot be size_t, because it supports negative
+ arguments, so it is normally the signed type of the same width as
+ size_t (sometimes declared as "intptr_t"). It doesn't much matter
+ though. Internally, we only call it with arguments less than half
+ the max value of a size_t, which should work across all reasonable
+ possibilities, although sometimes generating compiler warnings. See
+ near the end of this file for guidelines for creating a custom
+ version of MORECORE.
+
+MORECORE_CONTIGUOUS default: 1 (true)
+ If true, take advantage of fact that consecutive calls to MORECORE
+ with positive arguments always return contiguous increasing
+ addresses. This is true of unix sbrk. It does not hurt too much to
+ set it true anyway, since malloc copes with non-contiguities.
+ Setting it false when definitely non-contiguous saves time
+ and possibly wasted space it would take to discover this though.
+
+MORECORE_CANNOT_TRIM default: NOT defined
+ True if MORECORE cannot release space back to the system when given
+ negative arguments. This is generally necessary only if you are
+ using a hand-crafted MORECORE function that cannot handle negative
+ arguments.
+
+HAVE_MMAP default: 1 (true)
+ True if this system supports mmap or an emulation of it. If so, and
+ HAVE_MORECORE is not true, MMAP is used for all system
+ allocation. If set and HAVE_MORECORE is true as well, MMAP is
+ primarily used to directly allocate very large blocks. It is also
+ used as a backup strategy in cases where MORECORE fails to provide
+ space from system. Note: A single call to MUNMAP is assumed to be
+ able to unmap memory that may have be allocated using multiple calls
+ to MMAP, so long as they are adjacent.
+
+HAVE_MREMAP default: 1 on linux, else 0
+ If true realloc() uses mremap() to re-allocate large blocks and
+ extend or shrink allocation spaces.
+
+MMAP_CLEARS default: 1 on unix
+ True if mmap clears memory so calloc doesn't need to. This is true
+ for standard unix mmap using /dev/zero.
+
+USE_BUILTIN_FFS default: 0 (i.e., not used)
+ Causes malloc to use the builtin ffs() function to compute indices.
+ Some compilers may recognize and intrinsify ffs to be faster than the
+ supplied C version. Also, the case of x86 using gcc is special-cased
+ to an asm instruction, so is already as fast as it can be, and so
+ this setting has no effect. (On most x86s, the asm version is only
+ slightly faster than the C version.)
+
+malloc_getpagesize default: derive from system includes, or 4096.
+ The system page size. To the extent possible, this malloc manages
+ memory from the system in page-size units. This may be (and
+ usually is) a function rather than a constant. This is ignored
+ if WIN32, where page size is determined using getSystemInfo during
+ initialization.
+
+USE_DEV_RANDOM default: 0 (i.e., not used)
+ Causes malloc to use /dev/random to initialize secure magic seed for
+ stamping footers. Otherwise, the current time is used.
+
+NO_MALLINFO default: 0
+ If defined, don't compile "mallinfo". This can be a simple way
+ of dealing with mismatches between system declarations and
+ those in this file.
+
+MALLINFO_FIELD_TYPE default: size_t
+ The type of the fields in the mallinfo struct. This was originally
+ defined as "int" in SVID etc, but is more usefully defined as
+ size_t. The value is used only if HAVE_USR_INCLUDE_MALLOC_H is not set
+
+REALLOC_ZERO_BYTES_FREES default: not defined
+ This should be set if a call to realloc with zero bytes should
+ be the same as a call to free. Some people think it should. Otherwise,
+ since this malloc returns a unique pointer for malloc(0), so does
+ realloc(p, 0).
+
+LACKS_UNISTD_H, LACKS_FCNTL_H, LACKS_SYS_PARAM_H, LACKS_SYS_MMAN_H
+LACKS_STRINGS_H, LACKS_STRING_H, LACKS_SYS_TYPES_H, LACKS_ERRNO_H
+LACKS_STDLIB_H default: NOT defined unless on WIN32
+ Define these if your system does not have these header files.
+ You might need to manually insert some of the declarations they provide.
+
+DEFAULT_GRANULARITY default: page size if MORECORE_CONTIGUOUS,
+ system_info.dwAllocationGranularity in WIN32,
+ otherwise 64K.
+ Also settable using mallopt(M_GRANULARITY, x)
+ The unit for allocating and deallocating memory from the system. On
+ most systems with contiguous MORECORE, there is no reason to
+ make this more than a page. However, systems with MMAP tend to
+ either require or encourage larger granularities. You can increase
+ this value to prevent system allocation functions to be called so
+ often, especially if they are slow. The value must be at least one
+ page and must be a power of two. Setting to 0 causes initialization
+ to either page size or win32 region size. (Note: In previous
+ versions of malloc, the equivalent of this option was called
+ "TOP_PAD")
+
+DEFAULT_TRIM_THRESHOLD default: 2MB
+ Also settable using mallopt(M_TRIM_THRESHOLD, x)
+ The maximum amount of unused top-most memory to keep before
+ releasing via malloc_trim in free(). Automatic trimming is mainly
+ useful in long-lived programs using contiguous MORECORE. Because
+ trimming via sbrk can be slow on some systems, and can sometimes be
+ wasteful (in cases where programs immediately afterward allocate
+ more large chunks) the value should be high enough so that your
+ overall system performance would improve by releasing this much
+ memory. As a rough guide, you might set to a value close to the
+ average size of a process (program) running on your system.
+ Releasing this much memory would allow such a process to run in
+ memory. Generally, it is worth tuning trim thresholds when a
+ program undergoes phases where several large chunks are allocated
+ and released in ways that can reuse each other's storage, perhaps
+ mixed with phases where there are no such chunks at all. The trim
+ value must be greater than page size to have any useful effect. To
+ disable trimming completely, you can set to MAX_SIZE_T. Note that the trick
+ some people use of mallocing a huge space and then freeing it at
+ program startup, in an attempt to reserve system memory, doesn't
+ have the intended effect under automatic trimming, since that memory
+ will immediately be returned to the system.
+
+DEFAULT_MMAP_THRESHOLD default: 256K
+ Also settable using mallopt(M_MMAP_THRESHOLD, x)
+ The request size threshold for using MMAP to directly service a
+ request. Requests of at least this size that cannot be allocated
+ using already-existing space will be serviced via mmap. (If enough
+ normal freed space already exists it is used instead.) Using mmap
+ segregates relatively large chunks of memory so that they can be
+ individually obtained and released from the host system. A request
+ serviced through mmap is never reused by any other request (at least
+ not directly; the system may just so happen to remap successive
+ requests to the same locations). Segregating space in this way has
+ the benefits that: Mmapped space can always be individually released
+ back to the system, which helps keep the system level memory demands
+ of a long-lived program low. Also, mapped memory doesn't become
+ `locked' between other chunks, as can happen with normally allocated
+ chunks, which means that even trimming via malloc_trim would not
+ release them. However, it has the disadvantage that the space
+ cannot be reclaimed, consolidated, and then used to service later
+ requests, as happens with normal chunks. The advantages of mmap
+ nearly always outweigh disadvantages for "large" chunks, but the
+ value of "large" may vary across systems. The default is an
+ empirically derived value that works well in most systems. You can
+ disable mmap by setting to MAX_SIZE_T.

+
+ The "chunks" argument is optional (i.e., may be null, which is

+ cannot independently free elements.)
+
+ independent_comallac differs from independent_calloc in that each
+ element may have a different size, and also that it does not
+ automatically clear elements.
+
+ independent_comalloc can be used to speed up allocation in cases

+/* ----------------------- Chunk representations ------------------------ */
+
+/*
+ (The following includes lightly edited explanations by Colin Plumb.)
+
+ The malloc_chunk declaration below is misleading (but accurate and
+ necessary). It declares a "view" into memory allowing access to
+ necessary fields at known offsets from a given base.
+
+ Chunks of memory are maintained using a `boundary tag' method as
+ originally described by Knuth. (See the paper by Paul Wilson
+ ftp://ftp.cs.utexas.edu/pub/garbage/allocsrv.ps for a survey of such
+ techniques.) Sizes of free chunks are stored both in the front of
+ each chunk and at the end. This makes consolidating fragmented
+ chunks into bigger chunks fast. The head fields also hold bits
+ representing whether chunks are free or in use.
+
+ Here are some pictures to make it clearer. They are "exploded" to
+ show that the state of a chunk can be thought of as extending from
+ the high 31 bits of the head field of its header through the
+ prev_foot and PINUSE_BIT bit of the following chunk header.
+
+ A chunk that's in use looks like:
+
+ chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | Size of previous chunk (if P = 1) |
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |P|
+ | Size of this chunk 1| +-+
+ mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | |
+ +- -+
+ | |
+ +- -+
+ | :
+ +- size - sizeof(size_t) available payload bytes -+
+ : |
+ chunk-> +- -+
+ | |
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |1|
+ | Size of next chunk (may or may not be in use) | +-+
+ mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+
+ And if it's free, it looks like this:
+
+ chunk-> +- -+
+ | User payload (must be in use, or we would have merged!) |
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |P|
+ | Size of this chunk 0| +-+
+ mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | Next pointer |
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | Prev pointer |
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | :
+ +- size - sizeof(struct chunk) unused bytes -+
+ : |
+ chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | Size of this chunk |
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |0|
+ | Size of next chunk (must be in use, or we would have merged)| +-+
+ mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | :
+ +- User payload -+
+ : |
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ |0|
+ +-+
+ Note that since we always merge adjacent free chunks, the chunks
+ adjacent to a free chunk must be in use.
+
+ Given a pointer to a chunk (which can be derived trivially from the
+ payload pointer) we can, in O(1) time, find out whether the adjacent
+ chunks are free, and if so, unlink them from the lists that they
+ are on and merge them with the current chunk.
+
+ Chunks always begin on even word boundaries, so the mem portion
+ (which is returned to the user) is also on an even word boundary, and
+ thus at least double-word aligned.
+
+ The P (PINUSE_BIT) bit, stored in the unused low-order bit of the
+ chunk size (which is always a multiple of two words), is an in-use
+ bit for the *previous* chunk. If that bit is *clear*, then the
+ word before the current chunk size contains the previous chunk
+ size, and can be used to find the front of the previous chunk.
+ The very first chunk allocated always has this bit set, preventing
+ access to non-existent (or non-owned) memory. If pinuse is set for
+ any given chunk, then you CANNOT determine the size of the
+ previous chunk, and might even get a memory addressing fault when
+ trying to do so.
+
+ The C (CINUSE_BIT) bit, stored in the unused second-lowest bit of
+ the chunk size redundantly records whether the current chunk is
+ inuse. This redundancy enables usage checks within free and realloc,
+ and reduces indirection when freeing and consolidating chunks.
+
+ Each freshly allocated chunk must have both cinuse and pinuse set.
+ That is, each allocated chunk borders either a previously allocated
+ and still in-use chunk, or the base of its memory arena. This is
+ ensured by making all allocations from the the `lowest' part of any
+ found chunk. Further, no free chunk physically borders another one,
+ so each free chunk is known to be preceded and followed by either
+ inuse chunks or the ends of memory.
+
+ Note that the `foot' of the current chunk is actually represented
+ as the prev_foot of the NEXT chunk. This makes it easier to
+ deal with alignments etc but can be very confusing when trying
+ to extend or adapt this code.
+
+ The exceptions to all this are
+
+ 1. The special chunk `top' is the top-most available chunk (i.e.,
+ the one bordering the end of available memory). It is treated
+ specially. Top is never included in any bin, is used only if
+ no other chunk is available, and is released back to the
+ system if it is very large (see M_TRIM_THRESHOLD). In effect,
+ the top chunk is treated as larger (and thus less well
+ fitting) than any other available chunk. The top chunk
+ doesn't update its trailing size field since there is no next
+ contiguous chunk that would have to index off it. However,
+ space is still allocated for it (TOP_FOOT_SIZE) to enable
+ separation or merging when space is extended.
+
+ 3. Chunks allocated via mmap, which have the lowest-order bit
+ (IS_MMAPPED_BIT) set in their prev_foot fields, and do not set
+ PINUSE_BIT in their head fields. Because they are allocated
+ one-by-one, each must carry its own prev_foot field, which is
+ also used to hold the offset this chunk has within its mmapped
+ region, which is needed to preserve alignment. Each mmapped
+ chunk is trailed by the first two fields of a fake next-chunk
+ for sake of usage checks.

+ Each tree holding treenodes is a tree of unique chunk sizes. Chunks
+ of the same size are arranged in a circularly-linked list, with only
+ the oldest chunk (the next to be used, in our FIFO ordering)
+ actually in the tree. (Tree members are distinguished by a non-null
+ parent pointer.) If a chunk with the same size an an existing node
+ is inserted, it is linked off the existing node using pointers that
+ work in the same way as fd/bk pointers of small chunks.
+
+ Each tree contains a power of 2 sized range of chunk sizes (the
+ smallest is 0x100 <= x < 0x180), which is is divided in half at each
+ tree level, with the chunks in the smaller half of the range (0x100
+ <= x < 0x140 for the top nose) in the left subtree and the larger
+ half (0x140 <= x < 0x180) in the right subtree. This is, of course,
+ done by inspecting individual bits.
+
+ Using these rules, each node's left subtree contains all smaller
+ sizes than its right subtree. However, the node at the root of each
+ subtree has no particular ordering relationship to either. (The
+ dividing line between the subtree sizes is based on trie relation.)
+ If we remove the last chunk of a given size from the interior of the
+ tree, we need to replace it with a leaf node. The tree ordering
+ rules permit a node to be replaced by any leaf below it.
+
+ The smallest chunk in a tree (a common operation in a best-fit
+ allocator) can be found by walking a path to the leftmost leaf in
+ the tree. Unlike a usual binary tree, where we follow left child
+ pointers until we reach a null, here we follow the right child
+ pointer any time the left one is null, until we reach a leaf with
+ both child pointers null. The smallest chunk in the tree will be
+ somewhere along that path.
+
+ The worst case number of steps to add, find, or remove a node is
+ bounded by the number of bits differentiating chunks within
+ bins. Under current bin calculations, this ranges from 6 up to 21
+ (for 32 bit sizes) or up to 53 (for 64 bit sizes). The typical case

+/* ----------------------------- Segments -------------------------------- */
+
+/*
+ Each malloc space may include non-contiguous segments, held in a
+ list headed by an embedded malloc_segment record representing the
+ top-most space. Segments also include flags holding properties of
+ the space. Large chunks that are directly allocated by mmap are not
+ included in this list. They are instead independently created and
+ destroyed without otherwise keeping track of them.
+
+ Segment management mainly comes into play for spaces allocated by
+ MMAP. Any call to MMAP might or might not return memory that is
+ adjacent to an existing segment. MORECORE normally contiguously
+ extends the current space, so this space is almost always adjacent,
+ which is simpler and faster to deal with. (This is why MORECORE is
+ used preferentially to MMAP when both are available -- see
+ sys_alloc.) When allocating using MMAP, we don't use any of the
+ hinting mechanisms (inconsistently) supported in various
+ implementations of unix mmap, or distinguish reserving from
+ committing memory. Instead, we just ask for space, and exploit
+ contiguity when we get it. It is probably possible to do
+ better than this on some systems, but no general scheme seems
+ to be significantly better.
+
+ Management entails a simpler variant of the consolidation scheme
+ used for chunks to reduce fragmentation -- new adjacent memory is
+ normally prepended or appended to an existing segment. However,
+ there are limitations compared to chunk consolidation that mostly
+ reflect the fact that segment processing is relatively infrequent
+ (occurring only when getting memory from system) and that we
+ don't expect to have huge numbers of segments:
+
+ * Segments are not indexed, so traversal requires linear scans. (It
+ would be possible to index these, but is not worth the extra
+ overhead and complexity for most programs on most platforms.)
+ * New segments are only appended to old ones when holding top-most
+ memory; if they cannot be prepended to others, they are held in
+ different segments.
+
+ Except for the top-most segment of an mstate, each segment record
+ is kept at the tail of its segment. Segments are added by pushing
+ segment records onto the list headed by &mstate.seg for the
+ containing mstate.
+
+ Segment flags control allocation/merge/deallocation policies:
+ * If EXTERN_BIT set, then we did not allocate this segment,
+ and so should not try to deallocate or merge with others.
+ (This currently holds only for the initial segment passed
+ into create_mspace_with_base.)
+ * If IS_MMAPPED_BIT set, the segment may be merged with
+ other surrounding mmapped segments and trimmed/de-allocated
+ using munmap.
+ * If neither bit is set, then the segment was obtained using
+ MORECORE so can be merged with surrounding MORECORE'd segments
+ and deallocated/trimmed using MORECORE with negative arguments.

+/*
+ A malloc_state holds all of the bookkeeping for a space.
+ The main fields are:
+
+ Top
+ The topmost chunk of the currently active segment. Its size is
+ cached in topsize. The actual size of topmost space is
+ topsize+TOP_FOOT_SIZE, which includes space reserved for adding
+ fenceposts and segment records if necessary when getting more
+ space from the system. The size at which to autotrim top is
+ cached from mparams in trim_check, except that it is disabled if
+ an autotrim fails.
+
+ Designated victim (dv)
+ This is the preferred chunk for servicing small requests that
+ don't have exact fits. It is normally the chunk split off most
+ recently to service another small request. Its size is cached in
+ dvsize. The link fields of this chunk are not maintained since it
+ is not kept in a bin.
+
+ SmallBins
+ An array of bin headers for free chunks. These bins hold chunks
+ with sizes less than MIN_LARGE_SIZE bytes. Each bin contains
+ chunks of all the same size, spaced 8 bytes apart. To simplify
+ use in double-linked lists, each bin header acts as a malloc_chunk
+ pointing to the real first node, if it exists (else pointing to
+ itself). This avoids special-casing for headers. But to avoid
+ waste, we allocate only the fd/bk pointers of bins, and then use
+ repositioning tricks to treat these as the fields of a chunk.
+
+ TreeBins
+ Treebins are pointers to the roots of trees holding a range of
+ sizes. There are 2 equally spaced treebins for each power of two
+ from TREE_SHIFT to TREE_SHIFT+16. The last bin holds anything
+ larger.
+
+ Bin maps
+ There is one bit map for small bins ("smallmap") and one for
+ treebins ("treemap). Each bin sets its bit when non-empty, and
+ clears the bit when empty. Bit operations are then used to avoid
+ bin-by-bin searching -- nearly all "search" is done without ever
+ looking at bins that won't be selected. The bit maps
+ conservatively use 32 bits per map word, even if on 64bit system.
+ For a good description of some of the bit-based techniques used
+ here, see Henry S. Warren Jr's book "Hacker's Delight" (and
+ supplement at http://hackersdelight.org/). Many of these are
+ intended to reduce the branchiness of paths through malloc etc, as
+ well as to reduce the number of memory locations read or written.
+
+ Segments
+ A list of segments headed by an embedded malloc_segment record
+ representing the initial space.
+
+ Address check support
+ The least_addr field is the least address ever obtained from
+ MORECORE or MMAP. Attempted frees and reallocs of any address less
+ than this are trapped (unless INSECURE is defined).
+
+ Magic tag
+ A cross-check field that should always hold same value as mparams.magic.
+
+ Flags
+ Bits recording whether to use MMAP, locks, or contiguous MORECORE
+
+ Statistics
+ Each space keeps track of current and maximum system memory
+ obtained via MORECORE or MMAP.
+
+ Locking
+ If USE_LOCKS is defined, the "mutex" lock is acquired and released
+ around every public call using this mspace.

+ For security, the main invariant is that malloc/free/etc never
+ writes to a static address other than malloc_state, unless static
+ malloc_state itself has been corrupted, which cannot occur via
+ malloc (because of these checks). In essence this means that we
+ believe all pointers, sizes, maps etc held in malloc_state, but
+ check all of those linked or offsetted from other embedded data
+ structures. These checks are interspersed with main code in a way
+ that tends to minimize their run-time cost.
+
+ When FOOTERS is defined, in addition to range checking, we also
+ verify footer fields of inuse chunks, which can be used guarantee
+ that the mstate controlling malloc/free is intact. This is a
+ streamlined version of the approach described by William Robertson
+ et al in "Run-time Detection of Heap-based Overflows" LISA'03
+ http://www.usenix.org/events/lisa03/tech/robertson.html The footer
+ of an inuse chunk holds the xor of its mstate and a random seed,
+ that is checked upon calls to free() and realloc(). This is
+ (probablistically) unguessable from outside the program, but can be
+ computed by any code successfully malloc'ing any chunk, so does not
+ itself provide protection against code that has already broken
+ security through some other means. Unlike Robertson et al, we
+ always dynamically check addresses of all offset chunks (previous,
+ next, etc). This turns out to be cheaper than relying on hashes.

+/* -------------------- Alternative MORECORE functions ------------------- */
+
+/*
+ Guidelines for creating a custom version of MORECORE:
+
+ * For best performance, MORECORE should allocate in multiples of pagesize.
+ * MORECORE may allocate more memory than requested. (Or even less,
+ but this will usually result in a malloc failure.)
+ * MORECORE must not allocate memory when given argument zero, but
+ instead return one past the end address of memory from previous
+ nonzero call.
+ * For best performance, consecutive calls to MORECORE with positive
+ arguments should return increasing addresses, indicating that
+ space has been contiguously extended.
+ * Even though consecutive calls to MORECORE need not return contiguous
+ addresses, it must be OK for malloc'ed chunks to span multiple
+ regions in those cases where they do happen to be contiguous.
+ * MORECORE need not handle negative arguments -- it may instead
+ just return MFAIL when given negative arguments.
+ Negative arguments are always multiples of pagesize. MORECORE
+ must not misinterpret negative args as large positive unsigned
+ args. You can suppress all such calls from even occurring by defining
+ MORECORE_CANNOT_TRIM,
+
+ As an example alternative MORECORE, here is a custom allocator
+ kindly contributed for pre-OSX macOS. It uses virtually but not
+ necessarily physically contiguous non-paged memory (locked in,
+ present and won't get swapped out). You can use it by uncommenting
+ this section, adding some #includes, and setting up the appropriate
+ defines above:
+
+ #define MORECORE osMoreCore
+
+ There is also a shutdown routine that should somehow be called for
+ cleanup upon program exit.
+
+ #define MAX_POOL_ENTRIES 100
+ #define MINIMUM_MORECORE_SIZE (64 * 1024U)
+ static int next_os_pool;
+ void *our_os_pools[MAX_POOL_ENTRIES];
+
+ void *osMoreCore(int size)
+ {
+ void *ptr = 0;
+ static void *sbrk_top = 0;
+
+ if (size > 0)
+ {
+ if (size < MINIMUM_MORECORE_SIZE)
+ size = MINIMUM_MORECORE_SIZE;
+ if (CurrentExecutionLevel() == kTaskLevel)
+ ptr = PoolAllocateResident(size + RM_PAGE_SIZE, 0);
+ if (ptr == 0)
+ {
+ return (void *) MFAIL;
+ }
+ // save ptrs so they can be freed during cleanup
+ our_os_pools[next_os_pool] = ptr;
+ next_os_pool++;
+ ptr = (void *) ((((size_t) ptr) + RM_PAGE_MASK) & ~RM_PAGE_MASK);
+ sbrk_top = (char *) ptr + size;

+/* qsort.c
+ * (c) 1998 Gareth McCaughan
+ *
+ * This is a drop-in replacement for the C library's |qsort()| routine.
+ *
+ * Features:
+ * - Median-of-three pivoting (and more)
+ * - Truncation and final polishing by a single insertion sort
+ * - Early truncation when no swaps needed in pivoting step
+ * - Explicit recursion, guaranteed not to overflow
+ * - A few little wrinkles stolen from the GNU |qsort()|.
+ * - separate code for non-aligned / aligned / word-size objects
+ *
+ * This code may be reproduced freely provided
+ * - this file is retained unaltered apart from minor
+ * changes for portability and efficiency
+ * - no changes are made to this comment
+ * - any changes that *are* made are clearly flagged
+ * - the _ID string below is altered by inserting, after
+ * the date, the string " altered" followed at your option
+ * by other material. (Exceptions: you may change the name
+ * of the exported routine without changing the ID string.
+ * You may change the values of the macros TRUNC_* and
+ * PIVOT_THRESHOLD without changing the ID string, provided
+ * they remain constants with TRUNC_nonaligned, TRUNC_aligned
+ * and TRUNC_words/WORD_BYTES between 8 and 24, and
+ * PIVOT_THRESHOLD between 32 and 200.)
+ *
+ * You may use it in anything you like; you may make money
+ * out of it; you may distribute it in object form or as
+ * part of an executable without including source code;
+ * you don't have to credit me. (But it would be nice if
+ * you did.)
+ *
+ * If you find problems with this code, or find ways of
+ * making it significantly faster, please let me know!

+/* Some comments on the implementation.
+ * 1. When we finish partitioning the array into "low"
+ * and "high", we forget entirely about short subarrays,
+ * because they'll be done later by insertion sort.
+ * Doing lots of little insertion sorts might be a win
+ * on large datasets for locality-of-reference reasons,
+ * but it makes the code much nastier and increases
+ * bookkeeping overhead.
+ * 2. We always save the shorter and get to work on the
+ * longer. This guarantees that every time we push
+ * an item onto the stack its size is <= 1/2 of that
+ * of its parent; so the stack can't need more than
+ * log_2(max-array-size) entries.
+ * 3. We choose a pivot by looking at the first, last
+ * and middle elements. We arrange them into order
+ * because it's easy to do that in conjunction with
+ * choosing the pivot, and it makes things a little
+ * easier in the partitioning step. Anyway, the pivot
+ * is the middle of these three. It's still possible
+ * to construct datasets where the algorithm takes
+ * time of order n^2, but it simply never happens in
+ * practice.
+ * 3' Newsflash: On further investigation I find that
+ * it's easy to construct datasets where median-of-3
+ * simply isn't good enough. So on large-ish subarrays
+ * we do a more sophisticated pivoting: we take three
+ * sets of 3 elements, find their medians, and then
+ * take the median of those.
+ * 4. We copy the pivot element to a separate place
+ * because that way we can always do our comparisons
+ * directly against a pointer to that separate place,
+ * and don't have to wonder "did we move the pivot
+ * element?". This makes the inner loop better.
+ * 5. It's possible to make the pivoting even more
+ * reliable by looking at more candidates when n
+ * is larger. (Taking this to its logical conclusion
+ * results in a variant of quicksort that doesn't
+ * have that n^2 worst case.) However, the overhead
+ * from the extra bookkeeping means that it's just
+ * not worth while.
+ * 6. This is pretty clean and portable code. Here are
+ * all the potential portability pitfalls and problems
+ * I know of:
+ * - In one place (the insertion sort) I construct
+ * a pointer that points just past the end of the
+ * supplied array, and assume that (a) it won't
+ * compare equal to any pointer within the array,
+ * and (b) it will compare equal to a pointer
+ * obtained by stepping off the end of the array.
+ * These might fail on some segmented architectures.
+ * - I assume that there are 8 bits in a |char| when
+ * computing the size of stack needed. This would
+ * fail on machines with 9-bit or 16-bit bytes.
+ * - I assume that if |((int)base&(sizeof(int)-1))==0|
+ * and |(size&(sizeof(int)-1))==0| then it's safe to
+ * get at array elements via |int*|s, and that if
+ * actually |size==sizeof(int)| as well then it's
+ * safe to treat the elements as |int|s. This might
+ * fail on systems that convert pointers to integers
+ * in non-standard ways.
+ * - I assume that |8*sizeof(size_t)<=INT_MAX|. This
+ * would be false on a machine with 8-bit |char|s,
+ * 16-bit |int|s and 4096-bit |size_t|s. :-)

+ * RLE encoding for software colorkey and alpha-channel acceleration
+ *
+ * Original version by Sam Lantinga
+ *
+ * Mattias Engdegård (Yorick): Rewrite. New encoding format, encoder and
+ * decoder. Added per-surface alpha blitter. Added per-pixel alpha
+ * format, encoder and blitter.
+ *
+ * Many thanks to Xark and johns for hints, benchmarks and useful comments
+ * leading to this code.
+ *
+ * Welcome to Macro Mayhem.
+ */
+
+/*
+ * The encoding translates the image data to a stream of segments of the form
+ *
+ * <skip> <run> <data>
+ *
+ * where <skip> is the number of transparent pixels to skip,
+ * <run> is the number of opaque pixels to blit,
+ * and <data> are the pixels themselves.
+ *
+ * This basic structure is used both for colorkeyed surfaces, used for simple
+ * binary transparency and for per-surface alpha blending, and for surfaces
+ * with per-pixel alpha. The details differ, however:
+ *
+ * Encoding of colorkeyed surfaces:
+ *
+ * Encoded pixels always have the same format as the target surface.
+ * <skip> and <run> are unsigned 8 bit integers, except for 32 bit depth
+ * where they are 16 bit. This makes the pixel data aligned at all times.
+ * Segments never wrap around from one scan line to the next.
+ *
+ * The end of the sequence is marked by a zero <skip>,<run> pair at the *
+ * beginning of a line.
+ *
+ * Encoding of surfaces with per-pixel alpha:
+ *
+ * The sequence begins with a struct RLEDestFormat describing the target
+ * pixel format, to provide reliable un-encoding.
+ *
+ * Each scan line is encoded twice: First all completely opaque pixels,
+ * encoded in the target format as described above, and then all
+ * partially transparent (translucent) pixels (where 1 <= alpha <= 254),
+ * in the following 32-bit format:
+ *
+ * For 32-bit targets, each pixel has the target RGB format but with
+ * the alpha value occupying the highest 8 bits. The <skip> and <run>
+ * counts are 16 bit.
+ *
+ * For 16-bit targets, each pixel has the target RGB format, but with
+ * the middle component (usually green) shifted 16 steps to the left,
+ * and the hole filled with the 5 most significant bits of the alpha value.
+ * i.e. if the target has the format rrrrrggggggbbbbb,
+ * the encoded pixel will be 00000gggggg00000rrrrr0aaaaabbbbb.
+ * The <skip> and <run> counts are 8 bit for the opaque lines, 16 bit
+ * for the translucent lines. Two padding bytes may be inserted
+ * before each translucent line to keep them 32-bit aligned.
+ *
+ * The end of the sequence is marked by a zero <skip>,<run> pair at the
+ * beginning of an opaque line.

+ * I've tried to make this more reasonable, but I've run in to a lot

+ *
+ * The original issue is the code was written in pixels and not
+ * dialog units (DLUs). All DialogBox functions use DLUs, which
+ * vary based on the selected font (yay).
+ *
+ * According to MSDN, the most reliable way to convert is via
+ * MapDialogUnits, which requires an HWND, which we don't have
+ * at time of template creation.
+ *
+ * We do however have:
+ * The system font (DLU width 8 for me)
+ * The font we select for the dialog (DLU width 6 for me)
+ *
+ * Based on experimentation, *neither* of these return the value
+ * actually used. Stepping in to MapDialogUnits(), the conversion
+ * is fairly clear, and uses 7 for me.
+ *
+ * As a result, some of this is hacky to ensure the sizing is
+ * somewhat correct.
+ *
+ * Honestly, a long term solution is to use CreateWindow, not CreateDialog.
+ *
+
+ *
+ * In order to get text dimensions we need to have a DC with the desired font.

+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

+ PKG_CONFIG path to pkg-config utility
+ PKG_CONFIG_PATH
+ directories to add to pkg-config's search path
+ PKG_CONFIG_LIBDIR
+ path overriding pkg-config's built-in search path
+ SDL_CFLAGS C compiler flags for SDL, overriding pkg-config
+ SDL_LIBS linker flags for SDL, overriding pkg-config
+ XMKMF Path to xmkmf, Makefile generator for X Window System
+ CPP C preprocessor

+Relative mode testing
+=====================
+
+See test program at the bottom of this file.
+
+Initial tests:
+
+ - When in relative mode, the mouse shouldn't be moveable outside of the window.
+ - When the cursor is outside the window when relative mode is enabled, mouse
+ clicks should not go to whatever app was under the cursor previously.
+ - When alt/cmd-tabbing between a relative mode app and another app, clicks when
+ in the relative mode app should also not go to whatever app was under the
+ cursor previously.

+UTF-8 decoder capability and stress test
+----------------------------------------
+
+Markus Kuhn <http://www.cl.cam.ac.uk/~mgk25/> - 2003-02-19
+
+This test file can help you examine, how your UTF-8 decoder handles
+various types of correct, malformed, or otherwise interesting UTF-8
+sequences. This file is not meant to be a conformance test. It does
+not prescribes any particular outcome and therefore there is no way to
+"pass" or "fail" this test file, even though the texts suggests a
+preferable decoder behaviour at some places. The aim is instead to
+help you think about and test the behaviour of your UTF-8 on a
+systematic collection of unusual inputs. Experience so far suggests
+that most first-time authors of UTF-8 decoders find at least one
+serious problem in their decoder by using this file.
+
+The test lines below cover boundary conditions, malformed UTF-8
+sequences as well as correctly encoded UTF-8 sequences of Unicode code
+points that should never occur in a correct UTF-8 file.
+
+According to ISO 10646-1:2000, sections D.7 and 2.3c, a device
+receiving UTF-8 shall interpret a "malformed sequence in the same way
+that it interprets a character that is outside the adopted subset" and
+"characters that are not within the adopted subset shall be indicated
+to the user" by a receiving device. A quite commonly used approach in
+UTF-8 decoders is to replace any malformed UTF-8 sequence by a
+replacement character (U+FFFD), which looks a bit like an inverted
+question mark, or a similar symbol. It might be a good idea to
+visually distinguish a malformed UTF-8 sequence from a correctly
+encoded Unicode character that is just not available in the current
+font but otherwise fully legal, even though ISO 10646-1 doesn't
+mandate this. In any case, just ignoring malformed sequences or
+unavailable characters does not conform to ISO 10646, will make
+debugging more difficult, and can lead to user confusion.
+
+Please check, whether a malformed UTF-8 sequence is (1) represented at
+all, (2) represented by exactly one single replacement character (or
+equivalent signal), and (3) the following quotation mark after an
+illegal UTF-8 sequence is correctly displayed, i.e. proper
+resynchronization takes place immageately after any malformed
+sequence. This file says "THE END" in the last line, so if you don't
+see that, your decoder crashed somehow before, which should always be
+cause for concern.
+
+All lines in this file are exactly 79 characters long (plus the line
+feed). In addition, all lines end with "|", except for the two test
+lines 2.1.1 and 2.2.1, which contain non-printable ASCII controls
+U+0000 and U+007F. If you display this file with a fixed-width font,
+these "|" characters should all line up in column 79 (right margin).
+This allows you to test quickly, whether your UTF-8 decoder finds the
+correct number of characters in every line, that is whether each
+malformed sequences is replaced by a single replacement character.
+
+Note that as an alternative to the notion of malformed sequence used
+here, it is also a perfectly acceptable (and in some situations even
+preferable) solution to represent each individual byte of a malformed
+sequence by a replacement character. If you follow this strategy in
+your decoder, then please ignore the "|" column.
+
+
+Here come the tests: |
+ |
+1 Some correct UTF-8 text |
+ |
+(The codepoints for this test are: |
+ U+03BA U+1F79 U+03C3 U+03BC U+03B5 --ryan.) |
+ |
+You should see the Greek word 'kosme': "κόσμε" |
+ |
+ |
+2 Boundary condition test cases |
+ |
+2.1 First possible sequence of a certain length |
+ |
+(byte zero skipped...there's a null added at the end of the test. --ryan.) |
+ |
+2.1.2 2 bytes (U-00000080): "" |
+2.1.3 3 bytes (U-00000800): "ࠀ" |
+2.1.4 4 bytes (U-00010000): "𐀀" |
+ |
+(5 and 6 byte sequences were made illegal in rfc3629. --ryan.) |
+2.1.5 5 bytes (U-00200000): "ø" |
+2.1.6 6 bytes (U-04000000): "ü" |
+ |
+2.2 Last possible sequence of a certain length |
+ |
+2.2.1 1 byte (U-0000007F): "" |
+2.2.2 2 bytes (U-000007FF): "߿" |
+ |
+(Section 5.3.2 below calls this illegal. --ryan.) |
+2.2.3 3 bytes (U-0000FFFF): "" |
+ |
+(5 and 6 bytes sequences, and 4 bytes sequences > 0x10FFFF were made illegal |
+ in rfc3629, so these next three should be replaced with a invalid |
+ character codepoint. --ryan.) |
+2.2.4 4 bytes (U-001FFFFF): "÷¿¿¿" |
+2.2.5 5 bytes (U-03FFFFFF): "û¿¿¿¿" |
+2.2.6 6 bytes (U-7FFFFFFF): "ý¿¿¿¿¿" |
+ |
+2.3 Other boundary conditions |
+ |
+2.3.1 U-0000D7FF = ed 9f bf = "" |
+2.3.2 U-0000E000 = ee 80 80 = "" |
+2.3.3 U-0000FFFD = ef bf bd = "�" |
+2.3.4 U-0010FFFF = f4 8f bf bf = "" |
+ |
+(This one is bogus in rfc3629. --ryan.) |
+2.3.5 U-00110000 = f4 90 80 80 = "ô" |
+ |
+3 Malformed sequences |
+ |
+3.1 Unexpected continuation bytes |
+ |
+Each unexpected continuation byte should be separately signalled as a |
+malformed sequence of its own. |
+ |
+3.1.1 First continuation byte 0x80: "" |
+3.1.2 Last continuation byte 0xbf: "¿" |
+ |
+3.1.3 2 continuation bytes: "¿" |
+3.1.4 3 continuation bytes: "¿" |
+3.1.5 4 continuation bytes: "¿¿" |
+3.1.6 5 continuation bytes: "¿¿" |
+3.1.7 6 continuation bytes: "¿¿¿" |
+3.1.8 7 continuation bytes: "¿¿¿" |
+ |
+3.1.9 Sequence of all 64 possible continuation bytes (0x80-0xbf): |
+ |
+ "
|
+ |
+ ¡¢£¤¥¦§¨©ª«¬®¯ |
+ °±²³´µ¶·¸¹º»¼½¾¿" |
+ |
+3.2 Lonely start characters |
+ |
+3.2.1 All 32 first bytes of 2-byte sequences (0xc0-0xdf), |
+ each followed by a space character: |
+ |
+ "À Á Â Ã Ä Å Æ Ç È É Ê Ë Ì Í Î Ï |
+ Ð Ñ Ò Ó Ô Õ Ö × Ø Ù Ú Û Ü Ý Þ ß " |
+ |
+3.2.2 All 16 first bytes of 3-byte sequences (0xe0-0xef), |
+ each followed by a space character: |
+ |
+ "à á â ã ä å æ ç è é ê ë ì í î ï " |
+ |
+3.2.3 All 8 first bytes of 4-byte sequences (0xf0-0xf7), |
+ each followed by a space character: |
+ |
+ "ð ñ ò ó ô õ ö ÷ " |
+ |
+3.2.4 All 4 first bytes of 5-byte sequences (0xf8-0xfb), |
+ each followed by a space character: |
+ |
+ "ø ù ú û " |
+ |
+3.2.5 All 2 first bytes of 6-byte sequences (0xfc-0xfd), |
+ each followed by a space character: |
+ |
+ "ü ý " |
+ |
+3.3 Sequences with last continuation byte missing |
+ |
+All bytes of an incomplete sequence should be signalled as a single |
+malformed sequence, i.e., you should see only a single replacement |
+character in each of the next 10 tests. (Characters as in section 2) |
+ |
+3.3.1 2-byte sequence with last byte missing (U+0000): "À" |
+3.3.2 3-byte sequence with last byte missing (U+0000): "à" |
+3.3.3 4-byte sequence with last byte missing (U+0000): "ð" |
+3.3.4 5-byte sequence with last byte missing (U+0000): "ø" |
+3.3.5 6-byte sequence with last byte missing (U+0000): "ü" |
+3.3.6 2-byte sequence with last byte missing (U-000007FF): "ß" |
+3.3.7 3-byte sequence with last byte missing (U-0000FFFF): "ï¿" |
+3.3.8 4-byte sequence with last byte missing (U-001FFFFF): "÷¿¿" |
+3.3.9 5-byte sequence with last byte missing (U-03FFFFFF): "û¿¿¿" |
+3.3.10 6-byte sequence with last byte missing (U-7FFFFFFF): "ý¿¿¿¿" |
+ |
+3.4 Concatenation of incomplete sequences |
+ |
+All the 10 sequences of 3.3 concatenated, you should see 10 malformed |
+sequences being signalled: |
+ |
+ "Ààðøüßï¿÷¿¿û¿¿¿ý¿¿¿¿" |
+ |
+3.5 Impossible bytes |
+ |
+The following two bytes cannot appear in a correct UTF-8 string |
+ |
+3.5.1 fe = "þ" |
+3.5.2 ff = "ÿ" |
+3.5.3 fe fe ff ff = "þþÿÿ" |
+ |
+4 Overlong sequences |
+ |
+The following sequences are not malformed according to the letter of |
+the Unicode 2.0 standard. However, they are longer then necessary and |
+a correct UTF-8 encoder is not allowed to produce them. A "safe UTF-8 |
+decoder" should reject them just like malformed sequences for two |
+reasons: (1) It helps to debug applications if overlong sequences are |
+not treated as valid representations of characters, because this helps |
+to spot problems more quickly. (2) Overlong sequences provide |
+alternative representations of characters, that could maliciously be |
+used to bypass filters that check only for ASCII characters. For |
+instance, a 2-byte encoded line feed (LF) would not be caught by a |
+line counter that counts only 0x0a bytes, but it would still be |
+processed as a line feed by an unsafe UTF-8 decoder later in the |
+pipeline. From a security point of view, ASCII compatibility of UTF-8 |
+sequences means also, that ASCII characters are *only* allowed to be |
+represented by ASCII bytes in the range 0x00-0x7f. To ensure this |
+aspect of ASCII compatibility, use only "safe UTF-8 decoders" that |
+reject overlong UTF-8 sequences for which a shorter encoding exists. |
+ |
+4.1 Examples of an overlong ASCII character |
+ |
+With a safe UTF-8 decoder, all of the following five overlong |
+representations of the ASCII character slash ("/") should be rejected |
+like a malformed UTF-8 sequence, for instance by substituting it with |
+a replacement character. If you see a slash below, you do not have a |
+safe UTF-8 decoder! |
+ |
+4.1.1 U+002F = c0 af = "À¯" |
+4.1.2 U+002F = e0 80 af = "à¯" |
+4.1.3 U+002F = f0 80 80 af = "ð¯" |
+4.1.4 U+002F = f8 80 80 80 af = "ø¯" |
+4.1.5 U+002F = fc 80 80 80 80 af = "ü¯" |
+ |
+4.2 Maximum overlong sequences |
+ |
+Below you see the highest Unicode value that is still resulting in an |
+overlong sequence if represented with the given number of bytes. This |
+is a boundary test for safe UTF-8 decoders. All five characters should |
+be rejected like malformed UTF-8 sequences. |
+ |
+4.2.1 U-0000007F = c1 bf = "Á¿" |
+4.2.2 U-000007FF = e0 9f bf = "à¿" |
+4.2.3 U-0000FFFF = f0 8f bf bf = "ð¿¿" |
+4.2.4 U-001FFFFF = f8 87 bf bf bf = "ø¿¿¿" |
+4.2.5 U-03FFFFFF = fc 83 bf bf bf bf = "ü¿¿¿¿" |
+ |
+4.3 Overlong representation of the NUL character |
+ |
+The following five sequences should also be rejected like malformed |
+UTF-8 sequences and should not be treated like the ASCII NUL |
+character. |
+ |
+4.3.1 U+0000 = c0 80 = "À" |
+4.3.2 U+0000 = e0 80 80 = "à" |
+4.3.3 U+0000 = f0 80 80 80 = "ð" |
+4.3.4 U+0000 = f8 80 80 80 80 = "ø" |
+4.3.5 U+0000 = fc 80 80 80 80 80 = "ü" |
+ |
+5 Illegal code positions |
+ |
+The following UTF-8 sequences should be rejected like malformed |
+sequences, because they never represent valid ISO 10646 characters and |
+a UTF-8 decoder that accepts them might introduce security problems |
+comparable to overlong UTF-8 sequences. |
+ |
+5.1 Single UTF-16 surrogates |
+ |
+5.1.1 U+D800 = ed a0 80 = "í " |
+5.1.2 U+DB7F = ed ad bf = "í¿" |
+5.1.3 U+DB80 = ed ae 80 = "í®" |
+5.1.4 U+DBFF = ed af bf = "í¯¿" |
+5.1.5 U+DC00 = ed b0 80 = "í°" |
+5.1.6 U+DF80 = ed be 80 = "í¾" |
+5.1.7 U+DFFF = ed bf bf = "í¿¿" |
+ |
+5.2 Paired UTF-16 surrogates |
+ |
+5.2.1 U+D800 U+DC00 = ed a0 80 ed b0 80 = "í í°" |
+5.2.2 U+D800 U+DFFF = ed a0 80 ed bf bf = "í í¿¿" |
+5.2.3 U+DB7F U+DC00 = ed ad bf ed b0 80 = "í¿í°" |
+5.2.4 U+DB7F U+DFFF = ed ad bf ed bf bf = "í¿í¿¿" |
+5.2.5 U+DB80 U+DC00 = ed ae 80 ed b0 80 = "í®í°" |
+5.2.6 U+DB80 U+DFFF = ed ae 80 ed bf bf = "í®í¿¿" |
+5.2.7 U+DBFF U+DC00 = ed af bf ed b0 80 = "í¯¿í°" |
+5.2.8 U+DBFF U+DFFF = ed af bf ed bf bf = "􏿿" |
+ |
+5.3 Other illegal code positions |
+ |
+5.3.1 U+FFFE = ef bf be = "" |
+5.3.2 U+FFFF = ef bf bf = "" |
