As this points out, the answer is system dependent.  In particular,
select() exists only on 4.2BSD and V8 derived systems.  (I understand
System VII ... no, make that System V release 3 [cannot change a
standard! :-) ] for the Vax has something equivalent, but harder
to use.)  Under 4.1BSD, one can use the FIONREAD ioctl.  Under
System III one can fiddle with VTIME or something like that.
