void** ppv
);
Parameters
- riid
Reference identifier.

Pointer to the interface.
Return Value
Returns E_POINTER if ppv is invalid. Returns NOERROR if the query is successful.
If the query is unsuccessful and the requested interface is IMediaPosition or IMediaSeeking, returns an HRESULT from a call to CreatePosPassThru.
If the query is unsuccessful and the interface is not IMediaPosition or IMediaSeeking, returns E_NOINTERFACE.

This member function implements the INonDelegatingUnknown::INonDelegatingUnknown method. It overrides the CBasePin::NonDelegatingQueryInterface member function and passes references to the IPin, IQualityControl, IMediaPosition, IMediaSeeking, and IUnknown interfaces.
Override this class to return other interfaces on the object in the derived class.
