	This function can be used to detect if an object supports a particular COM interface derived from IUnknown.
template<typename T = IUnknown>
T *	GetInterfacePointer () const noexcept
bool	QueryInterface (REFIID riid, void **itf) const
	Queries a COM object for a pointer to one of its interface; identifying the interface by a reference to its interface identifier (IID). If the COM object implements the interface, then it returns a pointer to that interface after calling IUnknown::AddRef on it.
