CBaseFilter::QueryFilterInfo

Retrieves information about the filter.

HRESULT QueryFilterInfo(
  FILTER_INFO* pInfo
);

Parameters

• pInfo
  Pointer to a FILTER_INFO structure to fill in.

Return Values

Returns an HRESULT value.

Remarks

This member function implements the IBaseFilter::QueryFilterInfo method. It copies the filter's name from m_pName, and copies the pointer to the filter graph interface from m_pGraph into the FILTER_INFO structure before returning.

Note that the IFilterGraph interface passed out by this member function is reference counted, and so must be released when the caller has finished with it.

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 3.0 and later.
