IConnector::GetConnectedTo method (devicetopology.h)
The GetConnectedTo method gets the connector to which this connector is connected.
Syntax
HRESULT GetConnectedTo(
[out] IConnector **ppConTo
);
Parameters
[out] ppConTo
Pointer to a pointer variable into which the method writes the address of the IConnector interface of the other connector object. 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 GetConnectedTo call fails, *ppConTo is NULL.
Return value
If the method succeeds, it returns S_OK. If it fails, possible return codes include, but are not limited to, the values shown in the following table.
| Return code | Description |
|---|---|
|
Pointer ppConTo is NULL. |
|
This connector is not connected, or the other side of the connection is not another device topology (for example, a Software_IO connection). |
|
The device topology on the other side of the connection is not active (that is, the device state is not DEVICE_STATE_ACTIVE). |
Remarks
For code examples that call this method, see the implementations of the GetHardwareDeviceTopology and SelectCaptureDevice functions in Device Topologies.
For information about Software_IO connections, see ConnectorType Enumeration. For information about the HRESULT_FROM_WIN32 macro, see the Windows SDK documentation. For information about the DEVICE_STATE_NOTPRESENT device state, see DEVICE_STATE_XXX Constants.
