sdlSetError function
Set the SDL error message for the current thread.
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);
}
\param fmt a printf()-style message format string
\param ... additional parameters matching % tokens in the fmt
string, if
any
\returns always -1.
\since This function is available since SDL 2.0.0.
