SDL_SetError

Set the SDL error message for the current thread.

Header File

Defined in SDL_error.h

Syntax

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

Function Parameters

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

Return Value

(int) Returns always -1.

Remarks

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);
}

Version

This function is available since SDL 2.0.0.
