The naive solution if you're using Unix is just to set up a signal 
handler for the appropriate signal:

void sighandler (int signal)
{
  /* do whatever */
}


and then in your main code

signal (SIGINT, sighandler);


at least, that should work. I'm not too sure under DJGPP because of all 
the glitches associated with DOS. But since v2 aims for POSIX compliance, 
it should support this behavior.
