[Boost-users] [asio] how to check connection state

Hi boosters!

I've written a simple client-server example using 
boost::asio::ip::tcp::socket. I establish the connection using 
socket::connect() and close it using socket::close().

But how can I determine the current state of connection (Am I still 
connected or not?)

Is it sufficient to check whether the socket is open? Is there a 
function socket::is_open()?

Or do I have to track errors for disconnection events and set some 
is_connected-flag somewhere.

Btw what is the purpose of the keep_alive socket option?

Thanks in advance

Sascha
