NAME
SDL_MAIN_USE_CALLBACKS - Inform SDL to use the main callbacks instead of main.
HEADER FILE
Defined in SDL3/SDL_main.h
SYNOPSIS
#include "SDL3/SDL.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.
