virtual CBasePin* GetPin(
  int n
) PURE;

Parameters

  • n
    Number of the specified pin.

Return Values

Returns a pointer to the pin specified by the n parameter.

Remarks

Override this member function to return a pointer to the nth pin on this filter. CBaseFilter adds a reference to it, when necessary, before passing it to any other object. This member function is called by the base class CEnumPins::Next member function to retrieve pins for the IEnumPins interface, which is used by the filter graph manager.
