Hmm, not exactly sure what you mean.
In my code I have the dtors of my connection objects emit a message
when they are called. Since they use the shared_from_this trick
they are invoked when the overlapped structure is been deleted since
they are bound to them.
So I am pretty sure I can see when the call to destruct the overlapped
On the other hand I can see that the socket is closed properly since
the client receives the shutdown request.
I would be glad if you could give me another hint which kind of
debug message would be helpful to you.
On the other hand, perhaps some (mathematical) reasoning also can
help: If the socket is closed, which property guarantees that
the queued completion status invoked with zero timeout will
see the associated overlapped for sure?
Or put it another way: why not waiting infinitely when we are
sure there must be something pending? Why zero timeout?
