Detailed Description

An interface to an object that acts as a worker thread for an I/O completion port driven work queue. The life-cycle of an object that implements this interface is as follows: one call to Initialise() (and, if it returns true), 0 or many calls to Process() and then one call to Shutdown().

Public Member Functions
virtual bool	Initialise ()=0
	Called once when the thread is first started. The thread should perform any required initialisation and return true if it was able to initialise correctly and false if it has failed to initialise and should be shut down.
virtual void	Process (const ULONG_PTR completionKey, const DWORD numberOfBytes, OVERLAPPED *pOverlapped)=0
	Called when a work item needs to be processed by the thread.
virtual void	Shutdown ()=0
	Called when the thread is being shut down the thread can perform any required clean up tasks here.
Protected Member Functions
	~IIOCPWorkerThreadCallback ()
	We never delete instances of this interface; you must manage the lifetime of the class that implements it.
