I wrote a simple client and server to get system information (e.g. cpu, memory, etc.)

Client send 'cpu' to the server, then server will return cpu's information to client.

Now client send multiple commands to server one time, e.g. cpu, memory, database, hard disk. But sometimes server couldn't receive some type information (e.g. cpu, database), and the missed information type is not fixed every time.

So I want client to check whether ITransport.write() sends message to server successfully. If failed, client will resend the message to server.

ITransport.write() always succeeds. It may or may not call socket.send immediately, so it cannot tell you if the socket.send() succeeded or not.

What are you trying to do?
