Read the man page on select.  It tells the kernel to wake up your program 
when there is a key for you.

You have to remember that key-loops in unix are bad, because it means that 
the computer is spending so much time computing your loop that it (which 
it doesn't know is just waiting for a keypress) that it has less time to 
go and do work for other people.  In fact this is one of the primary 
problems with multitasking dos, is that everything is so used to doing 
keyboard input loops that the multitaskers end up switching to programs 
that aren't doing anything but sitting in a busy loop.
