Receives requests from a thread pool and passes them on to a worker object that is created and destroyed on each request.
This class and its members cannot be used in applications that execute in the Windows Runtime.

This class is a simple worker thread for use with CThreadPool. This class doesn't provide any request-handling capabilities of its own. Instead, it instantiates one instance of Worker per request and delegates the implementation of its methods to that instance.
The benefit of this class is that it provides a convenient way to change the state model for existing worker thread classes.
CThreadPool will create a single worker for the lifetime of the thread, so if the worker class holds state, it will hold it across multiple requests. By simply wrapping that class in the
CNonStatelessWorker template before using it with
CThreadPool, the lifetime of the worker and the state it holds is limited to a single request.
Implementation of WorkerArchetype::Execute.
void Execute( Worker::RequestType request, void* pvWorkerParam, OVERLAPPED* pOverlapped);
This method creates an instance of the Worker class on the stack and calls Initialize on that object. If the initialization is successful, this method also calls Execute and Terminate on the same object.
Implementation of WorkerArchetype::Initialize.
BOOL Initialize(void* /* pvParam */) throw();
Always returns TRUE.
This class does not do any initialization in
Implementation of WorkerArchetype::RequestType.
typedef Worker::RequestType RequestType;
This class handles the same type of work item as the class used for the Worker template parameter. See CNonStatelessWorker Overview for details.
Implementation of WorkerArchetype::Terminate.
void Terminate(void* /* pvParam */) throw();
This class does not do any cleanup in
