/* Include file for SDL quit event handling */
An SDL_QUITEVENT is generated when the user tries to close the application
window. If it is ignored or filtered out, the window will remain open.
If it is not ignored or filtered, it is queued normally and the window
is allowed to close. When the window is closed, screen updates will
complete, but have no effect.
SDL_Init() installs signal handlers for SIGINT (keyboard interrupt)
and SIGTERM (system termination request), if handlers do not already
exist, that generate SDL_QUITEVENT events as well. There is no way
to determine the cause of an SDL_QUITEVENT, but setting a signal
handler in your application will override the default generation of
quit events for that signal.
/* There are no functions directly affecting the quit event */
return 0 != SDL_PeepEvents(null, 0, SDL_PEEKEVENT, SDL_QUITMASK);
