Set the SDL error message for the current thread.
int SDL_SetError(SDL_PRINTF_FORMAT_STRING const char *fmt, ...) SDL_PRINTF_VARARG_FUNC(1);

... | additional parameters matching % tokens in the fmt string, if any |
Returns always -1.
Calling this function will replace any previous error message that was set.
This function always returns -1, since SDL frequently uses -1 to signify an failing result, leading to this idiom:
if (error_code) {
return SDL_SetError("This operation has failed: %d", error_code);
