SDL_SetError - Set the SDL error message for the current thread.

Defined in SDL3/SDL_error.h

#include "SDL3/SDL.h"

bool SDL_SetError(const char *fmt, ...);

Calling this function will replace any previous error message that was set.

This function always returns false, since SDL frequently uses false to signify a failing result, leading to this idiom:

if (error_code) {
return SDL_SetError("This operation has failed: %d", error_code);
}

	fmt		a printf()-style message format string.
	...		additional parameters matching % tokens in the fmt string, if any.

Returns false.

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
