ADLX_RESULT    QueryInterface (const wchar_t* interfaceId, void** ppInterface)

#	Direction	Name	Type	Description
1.	[in]	interfaceId	const wchar_t*	The identifier of the interface being requested.
#	Direction	Name	Type	Description
---	---	---	---	---
2.	[out]	ppInterface	void**	The address of a pointer to the returned interface. If the interface is not successfully returned, the method sets the dereferenced address *ppInterface to nullptr.

If the interface is successfully returned, ADLX_OK is returned.

If the interface is not successfully returned, an error code is returned.

Refer to ADLX_RESULT for success codes and error codes.

The returned interface must be discarded with Release when it is no longer needed.

In C++ when using a smart pointer for the returned interface there is no need to call Release because the smart pointer calls it internally.
