    how to block a socket indefinitely

    Hi everybody,

    When a socket is created, by default it is a blocking socket. Under blocking mode socket I/O operations, connect and accept operations all block until the operation in question is completed.
    I want to receive data periodically from a client. That is, the first time I receive data the socket is blocked in the accept function but the next time is not blocked anymore and I want that it waits for the next incoming data.
    I used the ioctlsocket function after the accept function this way:
    Code:
    AcceptSocket = SOCKET_ERROR;
    		while (AcceptSocket == SOCKET_ERROR)
    		{
    			AcceptSocket = accept(socketInTCP, NULL, NULL);
                            ioctlsocket=(socketInTCP, FIONBIO, &imode);
    		}
    but I get this error message at the ioctlsocket function: 10093, and I read that is because the WSAStartup() was wrong but it isn't so.

    Can you help me
    thank you very much.

    One way to do it would be to use select() or create a separate thread.

    can you explain me a little bit more? I think I can use this select function to have a server with concurrent clients but I haven't this. I have a server for an iterative client.

    thank you
