Stevens, W.R. 1992 "Advanced Programming in the UNIX Environment", Addison-Wesley,
advocates the use of select quite nicely.
Select works on writes and exceptions as well as reads. VTIME/VMIN only addresses
reads. Also,
a single select call can handle multiple file descriptors in one call. VTIME/VMIN
works fine, so does select.
Select's implementation varies a bit from O/S to O/S. Linux, for instance, changes the
timeval structure on return (to reflect elapsed time) where most other O/Ses leave it
unchanged.
