* \file SDL_loadso.h
* System dependent library loading routines
* Some things to keep in mind:
* \li These functions only work on C function names. Other languages may
* have name mangling and intrinsic language support that varies from
* compiler to compiler.
* \li Make sure you declare your function pointers with the same calling
* convention as the actual library function. Your code will crash
* mysteriously if you do not do this.
* \li Avoid namespace collisions. If you load a symbol from the library,
* it is not defined whether or not it goes into the global symbol
* namespace for the application. If it does and it conflicts with
* symbols in your code or other shared libraries, you will not get
* the results you expect. :)
