HRESULT GetState( DWORD dwMilliSecsTimeout , FILTER_STATE * State );
Parameters
- dwMilliSecsTimeout
- Duration of the time-out, in milliseconds.
- State
- Returned state of the filter.
Return Values
Returns S_OK.
Remarks
This member function implements the IMediaFilter::GetStatemethod. It returns the value of the m_Statedata member.
Filters should derive their filters from CBaseFilterand not from CBaseMediaFilter, so filters will not likely use this member function. Use CBaseFilter::GetStateinstead.
