pub unsafe extern "C" fn SDL_SetError(fmt: *const c_char, ...) -> bool
Expand description

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);
}

§Parameters

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

§Return value

Returns false.

§Thread safety

It is safe to call this function from any thread.
