Bind and Listen on an Available Port in a Range

See more Socket/SSL/TLS Examples

Demonstrates Socket.BindAndListenPortRange, which searches an inclusive port range for an available TCP port, binds it, and begins listening. It returns the selected port, or -1 on failure.

func chilkatTest() {
    let socket = CkoSocket()!

    //  Search the inclusive port range for an available TCP port, bind it, and begin listening.  The
    //  method returns the selected port, or -1 when no port can be bound.
    var boundPort: Int = socket.bindAndListenPortRange(beginPort: 5000, endPort: 5100, backLog: 25).intValue
    if boundPort < 0 {
        print("\(socket.lastErrorText!)")
        return
    }

    print("Listening on port \(boundPort)")
