IPort

The IPort interface is the generic interface for audio port drivers. All audio port drivers expose IPort as part of their lower edge. The adapter driver calls the initialization method on this interface. IPort inherits from the IUnknown interface.

The IPort interface provides a uniform means for initializing audio port drivers of all types. IPort is the base interface for the following port driver interfaces:

IPortDMus

IPortMidi

IPortTopology

IPortWaveCyclic

IPortWavePci

IPortWaveRT

Call PcNewPort to create a port object with one of these interfaces.

In addition to the methods that IPort inherits from the IUnknown interface, IPort supports the following methods:

IPort::GetDeviceProperty

IPort::Init

IPort::NewRegistryKey
