NAME¶

SDL_MAIN_USE_CALLBACKS - Inform SDL to use the main callbacks instead of main.

SYNOPSIS¶

#include <SDL3/SDL_main.h>

#define SDL_MAIN_USE_CALLBACKS 1

DESCRIPTION¶

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.

AVAILABILITY¶

This macro is used by the headers since SDL 3.2.0.
