NAME
SDL_MAIN_HANDLED - Inform SDL that the app is providing an entry point instead of SDL.
SYNOPSIS
#include <SDL3/SDL_main.h>
#define SDL_MAIN_HANDLED 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 the proper entry point for the platform, and all the other magic
details needed, like manually calling SDL_SetMainReady.
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.
