Demonstrates how to create a TCP/IP socket, listen on a port, accept an incoming connection, and send a "Hello World" message to the client.

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    listenSocket := chilkat.NewSocket()

    // Bind to a port and listen for incoming connections:
    // This example will listen at port 5555 and allows for a backlog
    // of 25 pending connection requests.

    if success != true {
        fmt.Println(listenSocket.LastErrorText())

    // Get the next incoming connection
    // Wait a maximum of 20 seconds (20000 millisec)
    // connectedSocket is a Socket
