CBaseInputPin::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 filter that is sending the quality-control message.

q

Quality structure that contains the quality-control message.

Return Value

Returns S_OK.

Remarks

Filters usually pass quality-control messages to an upstream output pin, not to an input pin. Therefore, this method returns S_OK without doing anything.

Requirements

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

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