 | |
|  *  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.
