SDL_GetError
Use this function to retrieve a message about the last error that occurred.
Syntax
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 user.
*
Code Examples
if (SDL_Init( SDL_INIT_EVERYTHING ) == -1) {
// 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.
*
Remarks
It is possible for multiple errors to occur before calling SDL_GetError(). Only the last error is returned.
