Perhaps you might propose a cross-platform asio API extension that could give you control at the times you want, using the completion-handler mechanism?

then there will be endless ways of loops that you need to integrated into asio. glib, qt, WIN32 message loop ... etc.

Understood. I am not proposing that specific message-loop code be absorbed into Asio. I am asking whether you (or any interested reader) might be able to define an extension API that permits / facilitates a consuming Asio application to integrate with any required message loop.

some thing like io_service::wait_events(); but , does not dispatch the event. I can run seperated thread to call this, then post message to gui thread, let gui thread run io_service::poll() to dispatch the handlers; if the hander is executed in gui thread, we can avoid lots of synchronization code between gui thread and asio thread( if io_service::run() has to be run in seperated thread. ).
