||
| 39 | * If it is not ignored or filtered, it is queued normally and the window |

||
| 43 | * SDL_Init() installs signal handlers for SIGINT (keyboard interrupt) |
||
| 44 | * and SIGTERM (system termination request), if handlers do not already |
||
| 45 | * exist, that generate ::SDL_QUIT events as well. There is no way |
||
| 46 | * to determine the cause of an ::SDL_QUIT event, but setting a signal |
||
| 47 | * handler in your application will override the default generation of |
||
| 48 | * quit events for that signal. |
