    Question Knowing when a client disconnects

    I am in the process of creating a server using C++ and TCPIP. I have created a socket, bound it to a port, set it to list and then accept dynamically created multiple connections (created as new sockets).

    How can I find out / be notified that a connection has been disconnected at the client end so that I can clean up the sockets?

    The client has gone when a read on the socket returns 0.

    I suggest beej's guide, there's a link to it in the links thread on this forum.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    If I had seen those links yesterday I wouldn't have wasted 25 on a TCP/IP Programming book that doesn't have the information anyway.

    Thanks for the info
