Retrieves the pin with the specified identifier.
HRESULT FindPin( LPCWSTR Id, IPin ** ppPin );
Parameters
- Id
- Identifier of the pin.
- ppPin
- Pointer to the
IPininterface 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::FindPinmember function. If the Idparameter is "In", it retrieves the input pin's IPinpointer; if the Idparameter is "Out", it retrieves the output pin's IPinpointer.
The ppPinparameter is set to NULL if the identifier cannot be matched.
