Your code will crash 34 * mysteriously if you do not do this. 35 * - Avoid namespace collisions. If you load a symbol from the library, 36 * it is not defined whether or not it goes into the global symbol 37 * namespace for the application. If it does and it conflicts with 38 * symbols in your code or other shared libraries, you will not get 39 * the results you expect. :) 40 */ 41 42 43 #ifndef _SDL_loadso_h 44 #define _SDL_loadso_h 45 46 #include "SDL_stdinc.h" 47 #include "SDL_error.h" 48 49 #include "begin_code.h" 50 /* Set up for C function definitions, even when using C++ */ 51 #ifdef __cplusplus 52 extern "C" { 53 #endif 54 55 /** 56 * This function dynamically loads a shared object and returns a pointer 57 * to the object handle (or NULL if there was an error). 58 * The 'sofile' parameter is a system dependent name of the object file. 59 */ 60 extern DECLSPEC void * SDLCALL SDL_LoadObject(const char *sofile); 61 62 /** 63 * Given an object handle, this function looks up the address of the 64 * named function in the shared object and returns it.
