<p> The OpenGL Registry contains specifications, header files, and
    related documentation for OpenGL and related APIs including GLU,
    GLX, and WGL. In addition to the core API specifications, many
    extensions to these APIs have been defined by vendors, groups of
    vendors, and the ARB. The Registry also contains specifications and
    header files for all registered extensions, written as modifications
    to the appropriate core API specifications. </p>

<p> The Registry also includes naming conventions, guidelines for
    creating new extensions and writing suitable extension
    specifications, and other documentation related to these APIs. </p>

<h2> <a name="headers"></a> API and Extension Header Files </h2>

<p> Because extensions vary from platform to platform and driver to
    driver, OpenGL developers can't expect interfaces for all extensions
    to be defined in the standard <tt>gl.h</tt>, <tt>glx.h</tt>, and
    <tt>wgl.h</tt> header files supplied with the OS / graphics drivers.
    Additional header files are provided here, including: </p>

<ul>
<li> <tt><a href="api/GL/glext.h">&lt;GL/glext.h&gt;</a></tt> - OpenGL
     1.2 and above compatibility profile and extension interfaces. </li>
<li> <tt><a href="api/GL/glcorearb.h">&lt;GL/glcorearb.h&gt;</a></tt> -
     OpenGL core profile and ARB extension interfaces, as described in
     appendix G.2 of the OpenGL 4.3 Specification. Does not include
     interfaces found only in the compatibility profile. </li>
<li> <tt><a href="api/GL/glxext.h">&lt;GL/glxext.h&gt;</a></tt> - GLX
     1.3 and above API and GLX extension interfaces. </li>
<li> <tt><a href="api/GL/wglext.h">&lt;GL/wglext.h&gt;</a></tt> - WGL
     extension interfaces. </li>
</ul>

<p> These headers define interfaces including enumerants; prototypes; and,
    for platforms supporting dynamic runtime extension queries, such as
    Linux and Microsoft Windows, function pointer typedefs. Please report
    problems as Issues in the <a
    href="index.php#repository">OpenGL-Registry</a> repository. </p>
