Other languages may * have name mangling and intrinsic language support that varies from * compiler to compiler. * - 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. * - 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. :) */ #ifndef _SDL_loadso_h #define _SDL_loadso_h #include "SDL_stdinc.h" #include "SDL_error.h" #include "begin_code.h" /* Set up for C function definitions, even when using C++ */ #ifdef __cplusplus /* *INDENT-OFF* */ extern "C" { /* *INDENT-ON* */ #endif /* This function dynamically loads a shared object and returns a pointer * to the object handle (or NULL if there was an error). * The 'sofile' parameter is a system dependent name of the object file. */ extern DECLSPEC void *SDLCALL SDL_LoadObject(const char *sofile); /* Given an object handle, this function looks up the address of the * named function in the shared object and returns it.
