Send a 4-byte Length Prefix over a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.SendCount, which sends a four-byte length prefix in network byte order. This is typically used to tell the peer how many bytes follow.

    success := false

    socket := chilkat.NewSocket()

    //  Connect to the server using TLS.
    bTls := true
    maxWaitMs := 5000
    success = socket.Connect("example.com",5000,bTls,maxWaitMs)
    if success == false {
        fmt.Println(socket.LastErrorText())
        socket.DisposeSocket()
        return
    }

    //  Send a four-byte length prefix in network byte order.  A common framing pattern is to send the
    //  number of bytes in a message before the message itself, so the peer knows exactly how many bytes
    //  to read.
    messageLength := 512
    success = socket.SendCount(messageLength)
    if success == false {
        fmt.Println(socket.LastErrorText())
        socket.DisposeSocket()
        return
    }

    fmt.Println("Length prefix sent.")

    socket.DisposeSocket()
