IConnector Interface

IConnector Interface

The IConnector interface represents a point of connection between components. The client obtains a reference to an IConnector interface by calling the IDeviceTopology::GetConnector or IConnector::GetConnectedTo method, or by calling the IPart::QueryInterface method with parameter iid set to REFIID IID_IConnector.

An IConnector interface instance can represent:

• An audio jack on a piece of hardware
• An internal connection to an integrated endpoint device (for example, a built-in microphone in a laptop computer)
• A software connection implemented through DMA transfers

The methods in the IConnector interface can describe various kinds of connectors. A connector has a type (a ConnectorType enumeration constant) and a subtype (a GUID obtained from the IPart::GetSubType method).

A part in a device topology can be either a connector or a subunit. The IPart interface provides methods that are common to connectors and subunits.

For code examples that use the IConnector interface, see the implementations of the GetHardwareDeviceTopology and SelectCaptureDevice functions in Device Topologies.

IConnector inherits from the IUnknown interface. In addition to the methods inherited from IUnknown, IConnector supports the following methods.
