This class is a worker thread class that queues requests to the queuing thread for completion asynchronously. To use this class, derive your class from it and override the CMsgThread::ThreadMessageProcmember function. The ThreadMessageProcmember function carries out each request. Your client functions and the ThreadMessageProcmember function must share a common definition of the parameters in the CMsgobject.
A negotiated mechanism tells the worker thread to exit. Typically, this will be one value of the CMsgclass's uMsgmessage code.
It is a good idea to send this message from the destructor of your derived class, and call the CMsgThread::WaitForThreadExitmember function before completing the destruction of the derived class.
