34 An SDL_QUITEVENT is generated when the user tries to close the application
35 window. If it is ignored or filtered out, the window will remain open.
36 If it is not ignored or filtered, it is queued normally and the window
37 is allowed to close. When the window is closed, screen updates will
38 complete, but have no effect.

40 SDL_Init() installs signal handlers for SIGINT (keyboard interrupt)
41 and SIGTERM (system termination request), if handlers do not already
42 exist, that generate SDL_QUITEVENT events as well. There is no way
43 to determine the cause of an SDL_QUITEVENT, but setting a signal
44 handler in your application will override the default generation of
45 quit events for that signal.
