Re: Question on select() and sockets

You can use blocking calls to send()/recv()/read()/write() if you don't care if you block in them - but I don't think that should ever be the case if you are using select().

Making the sockets non-blocking guarantees control over when you block (ie, in select()). Although I was writing about pipes in my recent reply to Edd, the same applies to sockets (first block of my reply):
