typedef SDL_AppResult (SDLCALL *SDL_AppInit_func)(void **appstate, int argc, char *argv[]);

These are used by SDL_EnterAppMainCallbacks. This mechanism operates behind the scenes for apps using the optional main callbacks. Apps that want to use this should just implement SDL_AppInit directly.

appstate

a place where the app can optionally store a pointer for future use.

argc

the standard ANSI C main's argc; number of elements in argv.

argv

the standard ANSI C main's argv; array of command line arguments.

Returns SDL_APP_FAILURE to terminate with an error, SDL_APP_SUCCESS to terminate with success, SDL_APP_CONTINUE to continue.

This datatype is available since SDL 3.2.0.
