[asio-users] asio::async_write & WriteHander

[Alfonso U. <aur...@in...>]

The documentation for the examples are... anyway...

The following code is from asio-0.3.8/src/examples/chat/chat_client.cpp

   void handle_write(const asio::error_code& error)
   {
     if (!error)
     {
       write_msgs_.pop_front();
       if (!write_msgs_.empty())
       {
         asio::async_write(socket_,
             asio::buffer(write_msgs_.front().data(),
               write_msgs_.front().length()),
             boost::bind(&chat_client::handle_write, this,
               asio::placeholders::error));
       }
     }
     else
     {
       do_close();
     }
   }

Just to make sure I'm reading this correctly, would it be correct to say 
that the write handler performs the write, and then sets itself as a 
write handler, so that after the write operation is done it is called 
again.  When called, the handler either repeats the process (if there 
are more messages), or if there are no messages, closes the socket.
