Expand description

Function pointer typedef for SDL_AppQuit.

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_AppEvent directly.

§Parameters

  • appstate: an optional pointer, provided by the app in SDL_AppInit.
  • result: the result code that terminated the app (success or failure).

§Availability

This datatype is available since SDL 3.2.0.
