This problem is a standard problem in network programming, and even though it
is not too difficult to find out how to solve it using the manuals, it is
annoying.
Attached is the network functionality of a program that I have written that is
a network server for generating opening books in a distributed fashion. I
have tried to remove as much domain-specific cruft as possible without
cutting away things that are useful to you. Even though this program is not
originally Open Source, feel free to use whatever part of this file as you
want to. This copy is hereafter officially under the GPL license.
Especially note the setting of socket options and the error-recovering and
signal-handling loop around select(). I also have pretty well tested code to
handle input- and output buffering.

PS
On second thought, I attached the client code as well. Enjoy.
