Re: Socket timeout value

[Scott Klement <klemscot@xxxxxxxxxxxx>]

The select() API is how you do "time-outs" on a socket.   You use select()
to wait for data to arrive.  If it doesn't arrive within your time-out
period, then you simply don't call recv().   The same technique can be
used with send().   If you want to be absolutely sure that your program
won't ever get "hung up" on the recv() or send() (or, for that matter on
connect() or accept()) use non-blocking sockets.

Here's a sample from the archives of using select() with recv():

One of these days I'll get around to explaining this better in the
tutorial (I've been asked this question many times) but alas I never seem
to have the time...
