Allright, I _am_ convinced. How do I ready ^C from the keyboard???

If this is some daemon program you can't. Perhaps that should be a daemon. Just make console client that will read commands from keyboard and send to your program. In single threaded client you can handle ^C if you like in signal handler without problem. That can be gui program if you like , but console one should be enough. You can implement eg: status, start, pause, quit and so. For now quit will be just fine, later you can add more commands. Make one listener thread in your program for such connections and that's it. Or just use telnet (this isn't safe though), but you can restrict connections. And don't forget to mask SIGINT :) Greetings, Bane.

This should be enough reason to scan for keyboard events instead. There is no guarantee that SIGINT would be sent only by keyboard.
