Retrieves information about the filter.
HRESULT QueryFilterInfo( FILTER_INFO * pInfo );
Parameters
- pInfo
- Pointer to a
FILTER_INFOstructure
to fill in.
Return Values
Returns an HRESULTvalue.
Remarks
This member function implements the IBaseFilter::QueryFilterInfomethod. It copies the filter's name from m_pName, and copies the pointer to the filter graph interface from m_pGraphinto the FILTER_INFOstructure before returning.
Note that the IFilterGraphinterface passed out by this member function is reference counted, and so must be released when the caller has finished with it.
