Bind and Listen on a Randomly Selected Unused Port

See more Socket/SSL/TLS Examples

Demonstrates how to bind and listen on a randomly selected unused port.

Note:The ListenPort property used in this example is available starting in Chilkat v9.5.0.59.

Go

    success := false

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

    listenSocket := chilkat.NewSocket()

    // Pass a value of 0 for the port number to randomly select
    // an unused port.
    // (The 2nd argument allows for a backlog of 25 pending connection requests when accepting connections.)
    success = listenSocket.BindAndListen(5555,25)
    if success != true {
        fmt.Println(listenSocket.LastErrorText())
        listenSocket.DisposeSocket()
        return
    }

    // Find out what port was chosen.
    // Note: The ListenPort propety was added in Chilkat v9.5.0.59
    listenPort := listenSocket.ListenPort()
    fmt.Println("Chosen listen port = ", listenPort)

    listenSocket.DisposeSocket()
