Inform SDL that the app is providing an entry point instead of SDL.
Defined in <SDL3/SDL_main.h>
#define SDL_MAIN_HANDLED 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 the proper entry point for the platform, and all the other magic details needed, like manually calling SDL_SetMainReady.
Please see 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 3.1.3.
