  This is very much an OS dependent problem, and I don't know the OS 
calls available to you.  There ought to be one that accepts a timeout
and does just what you ask.  If not, you may have to resort to getting
one OS thread to do a read, while another does a timeout, and whichever
finishes first kills the other.  That is a substantially trickier, and
also implementation dependent, problem.
