title: Using boost::asio::async_read with stdin?
body: <p>short question: I have a realtime-simulation which is running as a backround process and is connected with pipes to the calling pogramm. I want to send commands to that process using stdin to get certain information from it via stdout. Now because it is a real-time process, it has to be a non blocking input. Is boost::asio::async_read in conjunction with iostream::cin a good idea for this task?  how would I use that function if it is feasible? Any more suggestions?</p>
