Suppose you have a process, A, with a file descriptor (a socket, in my
case) and you want process B to have the file descriptor instead.  Is there
any way of transfering the file descriptor from one process into another?
Thanks!

Yes. Read all about it in Stevens books.

Note also that there are variations in the details across
implementations.  What system(s) do you want to do this on?

Cheers,

Probably Windows, according to OP's headers.

Rich, Amazon.ca says your book will be available 28/8/2004. Is that true?

Amazon.com says tomorrow (the 20th), so yes, it's true (mailing
delays notwithstanding).  I hope to be getting a few advance
copies today or tomorrow.

I'll post a general announcement once Amazon.com says they
have some in stock.

Thank you for asking.  I want to do this on Linux (2.4.21-4.0.1.ELsmp).

I'm also curious as to why Cvetkovic would want to plug someone else's
book instead of answering my (hopefully simple) question, but I digress...

Why would you assume this?  Perhaps you can tell that I'm using an
MS-Windows news client but that doesn't mean I want to do this on that
platform.  Indeed, "file descriptor" is a term absent from MS-Windows jargon
(instead, they refer to handles)...

Why am I recommending Stevens? Because his books about Unix and Network
programming are _the_ programming books for UNIX. I am certain the others
will agree with me.

Btw, the answer to that question is not that simple and depends also on the
platform.

Dragan

P.S. W. Richard Stevens is unfortunally dead, so he can benefit from my
"plug".

Dragan recommend Rich Stevens' books because they're among the best
for their subject matter.  Also, a simple question does not always
generate a simple answer.
