If it is ignored or filtered out, the window will remain open. If 27 * it is not ignored or filtered, it is queued normally and the window is 28 * allowed to close. When the window is closed, screen updates will complete, 29 * but have no effect. 30 * 31 * SDL_Init() installs signal handlers for SIGINT (keyboard interrupt) and 32 * SIGTERM (system termination request), if handlers do not already exist, 33 * that generate SDL_QUIT events as well. There is no way to determine the 34 * cause of an SDL_QUIT event, but setting a signal handler in your 35 * application will override the default generation of quit events for that 36 * signal. 37 */ 38 39 #ifndef SDL_quit_h_ 40 #define SDL_quit_h_ 41 42 #include "SDL_stdinc.h" 43 #include "SDL_error.h" 44 45 /* There are no functions directly affecting the quit event */ 46 47 #define SDL_QuitRequested() \ 48 (SDL_PumpEvents(), (SDL_PeepEvents(NULL,0,SDL_PEEKEVENT,SDL_QUIT,SDL_QUIT) > 0)) 49 50 #endif /* SDL_quit_h_ */
