Retrieves a CBasePinobject on the filter.
virtual CBasePin *GetPin( int n ) PURE;
Parameters
- n
- Number of the specified pin.
Return Values
Returns a pointer to the pin specified by the nparameter.
Remarks
Override this member function to return a pointer to the nth pin on this filter. CBaseFilteradds a reference to it, when necessary, before passing it to any other object. This member function is called by the base class CEnumPins::Nextmember function to retrieve pins for the IEnumPinsinterface, which is used by the filter graph manager.
