I am using the select method with winsock for a console RPG. I am wondering how to check if a client has suddenly disconnected. I have a book on network programming, but it is not very good. It focuses mostly on using Async and Completion Port methods. Please help!

IIRC, when a client disconnects, the readfds of the select() function will become activated and select() will return a non-zero result. Check through your readfds and you should find which one caused the message using FD_ISSET(). When you try to read from that socket, the number of bytes read will be 0. That tells you that your client has suddenly disconnected. Hope this helps.
