Other languages may 00029 * have name mangling and intrinsic language support that varies from 00030 * compiler to compiler. 00031 * \li Make sure you declare your function pointers with the same calling 00032 * convention as the actual library function. Your code will crash 00033 * mysteriously if you do not do this. 00034 * \li Avoid namespace collisions. If you load a symbol from the library, 00035 * it is not defined whether or not it goes into the global symbol 00036 * namespace for the application. If it does and it conflicts with 00037 * symbols in your code or other shared libraries, you will not get 00038 * the results you expect. :) 00039 */ 00040 00041 #ifndef _SDL_loadso_h 00042 #define _SDL_loadso_h 00043 00044 #include "SDL_stdinc.h" 00045 #include "SDL_error.h" 00046 00047 #include "begin_code.h" 00048 /* Set up for C function definitions, even when using C++ */ 00049 #ifdef __cplusplus 00050 extern "C" { 00051 #endif 00052 00053 /** 00054 * This function dynamically loads a shared object and returns a pointer 00055 * to the object handle (or NULL if there was an error). 00056 * The 'sofile' parameter is a system dependent name of the object file. 00057 */ 00058 extern DECLSPEC void *SDLCALL SDL_LoadObject(const char *sofile); 00059 00060 /** 00061 * Given an object handle, this function looks up the address of the 00062 * named function in the shared object and returns it.
