Sets the object containing the IQualityControlinterface that will receive quality-control messages.
HRESULT SetSink( IQualityControl * piqc );
Parameters
- piqc
- Pointer to the
IQualityControlinterface to which the notifications should be
sent.
Return Values
Base class returns NOERROR by default. The overriding member function should return an HRESULTvalue.
Remarks
This member function implements the IQualityControl::SetSinkmethod. The default implementation sets the m_pQSinkdata member to the piqcparameter passed in.
The IQualityControl::SetSinkmethod tells a filter where to send quality-control messages it receives. When no sink has been explicitly set or if the last call to CBasePin::SetSinkset the sink to NULL, the message should go upstream. The derived output pin class typically overrides CBasePin::Notifyto enable this.
