Overview
This function pointer is no longer valid after calling
SDL_UnloadObject ().
This function can only look up C function names. 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.
If the requested function doesn't exist, NULL is returned.
