Can anyone point me to a way to do this? Switch out of cooked mode. Seriously. A routine like kbhit() is only going to work usefully in raw or rare mode. > Have you tried using fileno(stdin) in a select() call with an immediate > return (when times=0)? It should do the trick of emulating kbhit(). I can't find an implementation of kbhit() to look at, but that's more or less what I'd expect it'd do. But a complete implementation should ioctl() into cbreak mode first.
