You can get A SIGIO signal for every keyboard, (or other input) event.
What you do with it is entirely up to you. Linux/Unix doesn't have
"callbacks", instead it has signals. It also has select() and poll(),
all useful for handling such events. If you want a time-stamp, you
call gettimeofday() in your signal handler.
