Retrieves a pointer to the connected pin, if there is one.
Syntax
HRESULT ConnectedTo(
IPin** ppPin
);
Parameters
- ppPin
IPin interface of the other pin (if any) that this pin is connected to.
Return Value
The base class returns S_OK if connected; otherwise, returns VFW_E_NOT_CONNECTED.
Remarks
This member function implements the IPin::ConnectedTo method.
It adds a reference to the connected IPin interface by calling the IUnknown::AddRef method, because each copy of an interface pointer has its reference incremented.
The calling application is responsible for calling IUnknown::Release on this interface when done with it.
