Winsock question

Hi! I am trying to create a chat application using the async socket mode ( I dont need more than 20 connections at a time so I didnt use overlapped mode). My chat program has a server and clients connected to it. The server returns to all clients the messages sent by a client and all the clients view the same message. The problem is that my chat server can resend a message which came from a client to only one client... I think I made a mistake in the FD_ACCEPT message:
case FD_ACCEPT: { sockaddr_in remoteAddr; int iRemoteAddrLen; iRemoteAddrLen = sizeof(remoteAddr); hRemoteSocket = accept(hSocket, (sockaddr*)&remoteAddr, &iRemoteAddrLen); } break;This code accepts all incoming clients but only lets me communicate with just one :wtf:! How can I communicate with more clients :confused:?(Do I have to create a new socket for all new clients? :omg: ) Thank you very much for your future answers! :sigh: Well... I am a beginner ... -

I am a beginner ...You may have to keep a reference to all the client sockets that is connected to your server sockets. You can use an array / list of socket descriptors for this. "A robust program is resistant to errors -- it either works correctly, or it does not work at all; whereas a fault tolerant program must actually recover from errors."

The socket you initially create on your server is just used to accept new connections from clients. When you call accept it will return a socket which you use to communicate with that client. You'll need to keep track of all sockets created by th accept fn. Phil
