Does anyone know of a good library I can get for free for windows 7
for udp communications?
UDP is easy; there is not much to do for such a library, so I think
you can just use Winsock. Most of the work is interacting with
whatever I/O multiplexer Windows has (whatever it has instead of
Unix's select()/poll()).
I was also wondering, does anyone want to work with me on a
designing a chat client/server program in c++ that uses udp?
A good idea in one way -- you can use your own project for
communicating with each other. You can even develop two different
clients and just cooperate on the protocol design.
This is off topic and a personal opinion, but I think that most people
who want to design an UDP-based protocol should think again and use
TCP. There are just too many protocol features you have to implement
on top of UDP, and you will not notice until it's too late.
Followup set to comp.protocols.tcp-ip, where they discuss these things.
