SDL_AppInit - App-implemented initial entry point for SDL_MAIN_USE_CALLBACKS

       This function is available since SDL 3.2.0.

       Apps implement this function when using

       SDL_MAIN_USE_CALLBACKS . If using a standard "main" function, you should not supply this.

       This  function  is  called by SDL once, at startup. The function should initialize whatever is necessary,
       possibly create windows and open audio devices, etc. The argc and argv parameters work  like  they  would
       with a standard "main" function.

       This  function  should  not go into an infinite mainloop; it should do any one-time setup it requires and
       then return.

       The app may optionally assign a pointer to *appstate . This pointer will be provided on every future call
       to the other entry points, to allow application state to be preserved between functions without  the  app
       needing to use a global variable. If this isn't set, the pointer will be NULL in future entry points.

       If  this  function  returns  SDL_APP_CONTINUE  , the app will proceed to normal operation, and will begin
       receiving repeated calls to

       SDL_AppIterate
        and SDL_AppEvent
        for the life of the program. If this function returns

       SDL_APP_FAILURE , SDL will call

       SDL_AppQuit
        and terminate the process with an exit code that reports an error to the platform. If it returns

       SDL_APP_SUCCESS , SDL calls SDL_AppQuit

       and terminates with an exit code that reports success to the platform.

       This function is called by SDL on the main thread.

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.

        apps.

       ( SDL_AppResult ) Returns SDL_APP_FAILURE

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