I am going through the tutorial on asio at
http://www.boost.org/doc/libs/1_37_0/doc/html/boost_asio/tutorial/tutdaytime1.html

and so far so good.  I have a question, the end iterator doesn't seem to 
be assigned a value, in the examples.  I was wondering how does it work..

e.g.

    tcp::resolver::iterator endpoint_iterator = resolver.resolve(query);
    tcp::resolver::iterator end;

    tcp::socket socket(io_service);
    boost::system::error_code error = boost::asio::error::host_not_found;
    while (error && endpoint_iterator != end)		// <<< Question:here
    {
      socket.close();
      socket.connect(*endpoint_iterator++, error);
    }

thanks.
