  30. * An ::SDL_QUIT event is generated when the user tries to close the application
  31. * window. If it is ignored or filtered out, the window will remain open.
  32. * If it is not ignored or filtered, it is queued normally and the window
  33. * is allowed to close. When the window is closed, screen updates will
  34. * complete, but have no effect.
  35. *
  36. * SDL_Init() installs signal handlers for SIGINT (keyboard interrupt)
  37. * and SIGTERM (system termination request), if handlers do not already
  38. * exist, that generate ::SDL_QUIT events as well. There is no way
  39. * to determine the cause of an ::SDL_QUIT event, but setting a signal
  40. * handler in your application will override the default generation of
  41. * quit events for that signal.
