OT: sockets

[Gernot Frisch]

Hi,

sorry, I didn't know where else to go...

I want to make a client/server program. The server should wait for
incoming messages, but if no messages are present, the recvfrom
function should return immediately. Any ideas? Should I start a worker
thread that stores messages received on a stack?

I'm new to sockets, can you point me to a good source?

Thank you,

This is a bit platfrom dependent, but I think that select() is used in both
Winsock and BSD so do this:
1) Make a non-blocking socket.
2) Run the RecvFrom() command.
3) Run the select() command to check if it is anything to read. Did
something similar with connect(). Should work. And next time post in a
group that is dedicated to the OS or whatever your runing.

Try using the ACE framework (http://www.cs.wustl.edu/~schmidt/ACE.html).
It's perfect for networked programming.
