If this pin is connected to another pin, the IPin::ConnectedTomethod returns a pointer to that pin.
HRESULT ConnectedTo( IPin ** ppPin );
Parameters
- ppPin
- [out] Pointer to an
IPinpointer to the
IPininterface of the other pin (if any) to which this pin is
connected. If there is no connection, the other pin interface
pointer will be NULL.
Return Values
Returns an HRESULTvalue that depends on the implementation. HRESULTcan be one of the following standard constants, or other values not listed.
E_FAIL Failure. E_POINTER Null pointer argument. E_INVALIDARG Invalid argument. E_NOTIMPL Method isn't supported. S_OK or NOERROR Success. Remarks
This method is implemented in the base classes by CBasePin::ConnectedTo. The interface returned by this method has had its reference count incremented. Be sure to use IUnknown::Releaseon the interface to decrement the reference count when you have finished using the interface.
