SDL_Unsupported - A macro to standardize error reporting on unsupported operations.

Defined in SDL3/SDL_error.h

#include "SDL3/SDL.h"

#define SDL_Unsupported() SDL_SetError( That operation is not supported")

This simply calls SDL_SetError () with a standardized error string, for convenience, consistency, and clarity.

It is safe to call this macro from any thread.

This macro is available since SDL 3.2.0.
