Re: Solaris 8 network programming problem

read/recv returning 0 on a socket means the other end has shutdown(), and

Or a 0 length message was received (non-SOCK_STREAM transports only)

Which is better read or recv ?

It doesn't matter in POSIX, although sometimes it's useful to use recv()
to imply to a programmer that the interface is expecting a socket and
read() to imply that it could be a network socket or a file.

read(2) is at liberty to concatenate UDP messages; recv(2) is not.
