miruga27 0:7fb6877b5d7c 37 * An ::SDL_QUIT event is generated when the user tries to close the application
miruga27 0:7fb6877b5d7c 38 * window. If it is ignored or filtered out, the window will remain open.
miruga27 0:7fb6877b5d7c 39 * If it is not ignored or filtered, it is queued normally and the window
miruga27 0:7fb6877b5d7c 40 * is allowed to close. When the window is closed, screen updates will
miruga27 0:7fb6877b5d7c 41 * complete, but have no effect.
miruga27 0:7fb6877b5d7c 42 *
miruga27 0:7fb6877b5d7c 43 * SDL_Init() installs signal handlers for SIGINT (keyboard interrupt)
miruga27 0:7fb6877b5d7c 44 * and SIGTERM (system termination request), if handlers do not already
miruga27 0:7fb6877b5d7c 45 * exist, that generate ::SDL_QUIT events as well. There is no way
miruga27 0:7fb6877b5d7c 46 * to determine the cause of an ::SDL_QUIT event, but setting a signal
miruga27 0:7fb6877b5d7c 47 * handler in your application will override the default generation of
miruga27 0:7fb6877b5d7c 48 * quit events for that signal.
