CBaseFilter::QueryFilterInfo
Microsoft DirectShow 9.0 |
CBaseFilter::QueryFilterInfo
The QueryFilterInfo method retrieves information about the filter. This method implements the IBaseFilter::QueryFilterInfo method.
Syntax
HRESULT QueryFilterInfo( FILTER_INFO *pInfo );
Parameters
pInfo
Pointer to a FILTER_INFO structure.
Return Value
Returns S_OK or E_POINTER.
Remarks
This method copies the filter's name from the CBaseFilter::m_pName member variable into the achName member of the FILTER_INFO structure. If m_pName is NULL, the method sets achName to L'\0'.
The method sets the pGraph member of the FILTER_INFO structure equal to the CBaseFilter::m_pGraph member variable, and increments the reference count. The caller must release the interface.
Requirements
** Header:** Declared in Amfilter.h; include Streams.h.
** Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
