CBasePin.Notify method

The Notify method notifies the pin that a quality change is requested. This method implements the IQualityControl::Notify method.

Syntax


HRESULT Notify(
   IBaseFilter *pSelf,
   Quality     q
);

Parameters

pSelf

Pointer to the IBaseFilter interface of the filter that delivered the quality-control message.

q

Specifies a Quality structure that contains the quality-control message.

Return value

The base class returns E_NOTIMPL.

Remarks

Output pins should override this method to accept quality-control messages.

If an external quality manager was installed (see CBasePin::SetSink), pass the message to that quality manager. Otherwise, the filter should handle the message itself, or pass the message upstream. For more information, see Quality-Control Management.

Requirements

Header

Amfilter.h (include Streams.h)

Library

Strmbase.lib (retail builds);
Strmbasd.lib (debug builds)
