CBasePin::Notify

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:** Declared in Amfilter.h; include Streams.h.

**  Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
