SDL_AppEvent_func.3type - Man Page

#include <SDL3/SDL_init.h>

typedef SDL_AppResult (SDLCALL *SDL_AppEvent_func)(void *appstate, SDL_Event *event);

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.

appstate

an optional pointer, provided by the app in SDL_AppInit.

event

the new event for the app to examine.

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.
