continuous return?

[Someone Something]

I'm trying to write something related to IRC. The thing is, I have one
thread receiving and another sending. But, how can I keep the caller of the
recv() function informed about what was last received so that it can all be
printed out. But, I no idea how I can accomplish this. I was thinking about
getting one variable that was constantly updated with the latest line that
was recved and that the variable would be  a member of the class so other
functions/classes can access it
