Hi all,

I would like to adapt my class to asio for offering async_do_something(param, callback) interfaces. [...]Do I have other choices? All suggestions are welcome.

I'm not entirely sure what you are trying to do. But maybe this helps a bit: I explained at < http://en.highscore.de/cpp/boost/asio.html#asio_extensions> how to create your own Boost.Asio I/O service. I also gave a presentation once about the different possibilities - see < https://github.com/boostcon/2011_presentations/raw/master/wed/creating_boost...

Hi Boris, Following your example, I have written my own extension. I found that when I register signal handler for shutdown my application manually, the application required ctrl-C twice to be shutdown. Then I go back to check the example, adding the same signal handler - it acted the same way. Should I book all io_service(s) for stop them externally? Here is a the example modified that uses sleep() rather than Windows API. http://gais4.cs.ccu.edu.tw/~yangacer/asio_ext.tar.gz Best wishes, Acer.
