Comment: hm, isn't that more accurate? does really EVERY sdl function support error handling? would every function even need to?

SDL_GetError
Use this function to retrieve a message about the last error that occurred.
Syntax
const char* SDL_GetError(void)
Return Value
Returns a message with information about the specific error that occurred, or an empty string if there hasn't been an error since the last call to SDL_ClearError().
This string is statically allocated and must not be freed by the application.
Code Examples
if (SDL_Init( SDL_INIT_EVERYTHING ) < 0) {
// Unrecoverable error, exit here.
printf("SDL_Init failed: %s\n", SDL_GetError());
}
Note: Although this example uses SDL_Init(), SDL_GetError() provides an error message for any failed SDL operation which supports error reporting, see the wiki page for each particular SDL function.
Remarks
It is possible for multiple errors to occur before calling SDL_GetError(). Only the last error is returned.
