CTransformFilter::FindPin

  • Article

Retrieves the pin with the specified identifier.

HRESULT FindPin(
  LPCWSTR Id,
  IPin** ppPin 
);

Parameters

  • Id
    Identifier of the pin.
  • ppPin
    Pointer to the IPin interface for this pin after the filter has been restored.

Return Values

Returns NOERROR if the pin name was found; otherwise, returns VFW_E_NOT_FOUND.

Remarks

This member function overrides the CBaseFilter::FindPin member function. If the Id parameter is "In", it retrieves the input pin's IPin pointer; if the Id parameter is "Out", it retrieves the output pin's IPin pointer.

The ppPin parameter is set to NULL if the identifier cannot be matched.
