Hello, All!

What are the benefits/drawbacks of using read() on socket operations, except
it's a general way for dealing with file descriptors? What about portability
etc.?

With best regards, Roman Mashak.  E-mail: mrv@tusur.ru

recv() takes an extra flags parameter.  That's the only difference.

I assume, both functions are equally portable?

For all Unix(-like) systems, yes. For Windows, no.

On Unix, read or recv will do exactly the same (apart from the flags
thing). On Windows, read() on a socket is not allowed. So, for
portability it is better to use recv for all sockets.
