Right, which is why I'm asking this question. When thinking about it a bit,
I can't see a compelling argument for combining nbio with the use of
select() - on the contrary it seems to require some tricky extra effort.
You're basically basing that assumption on that recv() and send() will return
and behave identically if it was blocking.
And if they would return immediately in blocking mode as it does in
non-blocking mode, they would behave the same as the code does now and we
would gain nothing by switching!
But the reality is that blocking sockets do in fact cause send(), recv() and
friends to block at times when non-blocking don't and that's the reason. Let
me for example quote a little piece from the send() man page:
When the message does not fit into the send buffer of the socket,
send() normally blocks, unless the socket has been placed in non-block‐
ing I/O mode.
