CBasePin::ConnectedTo (Windows Embedded CE 6.0)

1/6/2010

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.
