I have the following code and it terminates as expected. When I call the destructor it interrupts the thread.

 

But if I change the this_thread::sleep to this_thread::yield the join() never happens and the program hangs.

 

I must be misunderstanding yield. But I really don’t want a sleep if possible.

 

Thanks,

John

 

MessageQueueHandler::~MessageQueueHandler()

{

    // Terminate the thread

    pMessageQueueInputThread->interrupt();

    pMessageQueueInputThread->join();

    delete pMessageQueueInputThread;

}

void MessageQueueHandler::MessageQueueInputThread()

{

    unsigned int receivedSize;

    unsigned int priority;

    char buffer[queueMaximumMessageSize];

    boost::this_thread::interruption_enabled();

    try

    {

        while(1)

        {

            // Process all messages in the queue

            while(inputMessageQueue->try_receive(buffer, queueMaximumMessageSize, receivedSize, priority))

            {

                BaseMessage * msg = reinterpret_cast<BaseMessage*>(buffer);

                callbackTable->DispatchMessage(msg);

                boost::this_thread::interruption_point();

            }

            // Give other threads a chance to run

            // This is also an interruption point

            boost::this_thread::sleep(boost::posix_time::millisec(50)); çHere

        }

    }

    catch(boost::thread_interrupted const&)

    {

        return;

    }

}
