template<typename T>
__forceinline static HRESULT AsIID(
   _In_ T* implements,
   REFIID riid,
   _Deref_out_ void **ppvObject
);

T
A type that implements the interface ID specified by parameter riid.

implements
A variable of the type specified by template parameter T.

riid
The interface ID to retrieve.

ppvObject
If this operation is successful, a pointer-to-a-pointer to the interface specified by parameter riid.

S_OK if successful; otherwise, an HRESULT that describes the error.

Retrieves a pointer to the specified interface ID.

T
The type of the implements parameter.

implements
Pointer to the type specified by parameter T.

iidCount
