Re: Testing socket for disconnect

To answer you first question -

as I understand it, there's no way to tell if the socket is still
connected without select()-ing* on it. So you will need some sort of
session-layer protocol no-op command that can be sent at intervals to
poll for (detect) disconnections.

I may be wrong!

* or kqueue(), poll(), epoll() etc, performed by boost::asio
