[asio-users] using a demuxer to poll

[Arvid N. <c9...@cs...>]

Hi.

I want to use one of my demuxers to poll the messages received on any  
of its sockets. i.e. have the same semantics as calling select() with  
a timeout of 0. I'm doing it like this:

    asio::deadline_timer t(m_demuxer, milliseconds(0));
    t.async_wait(bind(&asio::demuxer::interrupt, ref(m_demuxer)));
    m_demuxer.run();
    m_demuxer.reset();

Does this guarantee that all pending socket events are handled before  
the timer event is handled and the demuxer is aborted? If, not is  
there a better way of achieving what I want?

And another question, is there a reason why run doesn't call reset()  
before it quits? are there any operations in the demuxer that makes  
sense only when it's in the state of "just returned from run, but not  
reset"? or is the reset() operation expensive so one may want to skip  
it if run() is not to be called again?

thanks
