BOOL VDDInitialize	(	IN HANDLE	Module,
		IN DWORD	Reason,
		IN LPVOID	Reserved
	)

VDD initialization und unloading.

This function is called whenever the VDD is loaded or unloaded. It ensures that the driver is loaded to be able to call its functions.

Parameters

Module	Handle of the module; this is not used.
Reason	DLL_PROCESS_ATTACH if the DLL is loaded, DLL_PROCESS_DETACH if it is unloaded.
Reserved	Not used.

Returns

Returns TRUE on success, else FALSE.
