Other languages may 29 * have name mangling and intrinsic language support that varies from 30 * compiler to compiler. 31 * \li Make sure you declare your function pointers with the same calling 32 * convention as the actual library function. Your code will crash 33 * mysteriously if you do not do this. 34 * \li Avoid namespace collisions. If you load a symbol from the library, 35 * it is not defined whether or not it goes into the global symbol 36 * namespace for the application. If it does and it conflicts with 37 * symbols in your code or other shared libraries, you will not get 38 * the results you expect. :) 39 */ 40 41 #ifndef _SDL_loadso_h 42 #define _SDL_loadso_h 43 44 #include "SDL_stdinc.h" 45 #include "SDL_error.h" 46 47 #include "begin_code.h" 48 /* Set up for C function definitions, even when using C++ */ 49 #ifdef __cplusplus 50 extern "C" { 51 #endif 52 53 /** 54 * This function dynamically loads a shared object and returns a pointer 55 * to the object handle (or NULL if there was an error). 56 * The 'sofile' parameter is a system dependent name of the object file. 57 */ 58 extern DECLSPEC void *SDLCALL SDL_LoadObject(const char *sofile); 59 60 /** 61 * Given an object handle, this function looks up the address of the 62 * named function in the shared object and returns it.
