I want to check the keyboard for input (using gcc of course) without
actually reading (ie: getc etc..). The unix FAQ suggests looking at
the FIONREAD ioctl or using select() and the C FAQ states that this is
a purely OS dependant question.

What is best for Linux? Can this be non-blocking? A snippet of code
for this would be great since I have not had to do this kind of thing
before. Thanks.
