If I have an asynchronous state machine running in another thread and I send it an event, is there any way to have the sending thread block until the event is processed? I need to use an asynchoronous machine because the rest of my app is threaded but yet there are points where I must synchronize to know the machine is in a certain state before moving on.
Moreover, how do I actually extract information from the state machine? Since fifo_scheduler<>::processor_handle is a weak_ptr<> I can't use it to query the state of the machine or extract any machine-specific information (such as elapsed time in the StopWatch example, if it were asynchronous). -Dave
