miruga27 0:dda4f4550403 23 * \file SDL_loadso.h
miruga27 0:dda4f4550403 24 *
miruga27 0:dda4f4550403 25 * System dependent library loading routines
miruga27 0:dda4f4550403 26 *
miruga27 0:dda4f4550403 27 * Some things to keep in mind:
miruga27 0:dda4f4550403 28 * \li These functions only work on C function names. Other languages may
miruga27 0:dda4f4550403 29 * have name mangling and intrinsic language support that varies from
miruga27 0:dda4f4550403 30 * compiler to compiler.
miruga27 0:dda4f4550403 31 * \li Make sure you declare your function pointers with the same calling
miruga27 0:dda4f4550403 32 * convention as the actual library function. Your code will crash
miruga27 0:dda4f4550403 33 * mysteriously if you do not do this.
miruga27 0:dda4f4550403 34 * \li Avoid namespace collisions. If you load a symbol from the library,
miruga27 0:dda4f4550403 35 * it is not defined whether or not it goes into the global symbol
miruga27 0:dda4f4550403 36 * namespace for the application. If it does and it conflicts with
miruga27 0:dda4f4550403 37 * symbols in your code or other shared libraries, you will not get
miruga27 0:dda4f4550403 38 * the results you expect. :)
