Winsock/MS question

[halla]

Well im learning Winsock and all of that... made a basic chat program. It is chat between a server and a client. But it only supports one client. I looked up stuff and people said to use an array of winsock to get more connections. Is this the way its done on MS or is it done another way?

Also since im starting from scratch should I just learn that IOCP instead since its supposed to be faster?

Thanks
