Does a new watcher see old unhandled events?

Question

If I have a socket and someone sent data to it that I didn't yet handle via read(), and now I make an ev_io watcher for it and run it, will the callback fire?

I don't know the answer to your question as I've never used libev. But I can suggest in the absence of this knowledge you might try to simulate the scenario and see what happens. :-)

It's level-triggered, not edge-triggered, so the callback will fire rapidly until all the pending data was read.
