Hi Bill,

In this case I suggest to use
- kbhit() and cgetc() to detect the Ctrl-C
- exit() to quit if Ctrl-C was detected
- atexit() to run custom cleanup code

Not directly related but there's also doesclrscrafterexit() that allows you
determine if the user will be able to read output from your program after
exit - i.e. an error message. You can call it i.e. from your atexit()
function and call cgetc() if it returns true having the user acknowledge
that he has read the message.

Regards,
Oliver
