SDL_MAIN_USE_CALLBACKS - Man Page

Defined in SDL3/SDL_main.h

#include "SDL3/SDL.h"

#define SDL_MAIN_USE_CALLBACKS 1

SDL does not define this macro, but will check if it is defined when including SDL_main.h . If defined, SDL will expect the app to provide several functions: SDL_AppInit ,

SDL_AppEvent , SDL_AppIterate , and

SDL_AppQuit . The app should not provide a main function in this case, and doing so will likely cause the build to fail.

Please see [README/main-functions](README/main-functions), (or docs/README-main-functions.md in the source tree) for a more detailed explanation.

This macro is used by the headers since SDL 3.2.0.
