LPUNKNOWN pUnk,

- pUnk
Pointer to LPUNKNOWN.
- phr
Pointer to an HRESULT value in which to return resulting information.
Return Value
Returns a pointer to a new Component Object Model (COM) object.
Remarks
This member function is required to create objects using the class factory. It calls the class constructor.
The phr parameter is modified only if a failure occurs. If it is a failure code on input, construction can be terminated, but the destructor is called by the creator when the HRESULT error is detected.
