[Boost-users] boost::asio::io_service - cancel posted work

Subject: [Boost-users] boost::asio::io_service - cancel posted work

I posted an async_accept to my io_service.
The async_accept gets posted again to listen for incoming connections every 
time it completes.

I was under the impression that calling io_service::stop, would be the way to 
stop listening.

When debugging, I see that a function object was created when I called bind 
inside my async_accept call.

That function object contains a smart pointer to the instance of the object to 
whom the method to call back belongs.

Since the callback never happens, my instance never gets destroyed.

How do I effectively cancel any outstanding work the io_service has posted to 
it, such that the smart pointer in the function object that the bind created 
will lose its reference count?

In debugging, the callback never gets called after stop, not does the 
reference count in the smart pointer decrement.
