c++ - I/O in concurrent program

Question

I'm working on a concurrent program; it has two threads, one of which listens messages from a server and the other one sends messages to it. I need to obtain commands from the user (using cin?) and show messages coming from the server both at the same time.

How can I handle that situation? The problem is that if I'm reading a command from the user when a message comes, the user's input is messed up with other stuff.

Thanks in advance

Some alternatives

1. have your command dump all the messages that have occurred since the last invocation of the command. That way the output is finite.

2. have your cli command monitor all traffic continuously until ctrl-c (or some other key combination) is pressed then it reverts back to your application's cli prompt.

3. have your cli command send data to a file and monitor that with a tail type tool
