Re: Single UDP sockets : duplex capable?

2006/11/28, Garrett Cooper <youshi10@xxxxxxxxxxxxxxxx>:
Hello,

Just wondering, abstractly..

Both sides can read from and write to the socket file descriptor.
You'll need to develop a protocol to determine when either given side
is expecting to receive or to send data (if both sides sit around in
read(2), you're not going to get much done) :)

--dho

-------------------------
| A -[socket (UDP)]-> B |
-------------------------

A creates a UDP socket (call it 's1') to talk to B.

Can B use the same socket ('s2') to talk to A using read(2) or
recv(2), or does A have to accept(2) traffic from B using a different
socket?

The programming language I'm using is C (not C++).

Thanks,
-Garrett
