IPart::GetTopologyObject

The GetTopologyObject method gets a reference to the IDeviceTopology interface of the device-topology object that contains this part.

HRESULT GetTopologyObject(
  IDeviceTopology  **ppTopology
);

Parameters

ppTopology

[out]  Pointer to a pointer variable into which the method writes the address of the IDeviceTopology interface of the device-topology object. The caller obtains a counted reference to the interface from this method. Through this method, the caller obtains a counted reference to the interface. The caller is responsible for releasing the interface, when it is no longer needed, by calling the interface's Release method. If the GetTopologyObject call fails, *ppTopology is NULL.

Return Value
