IPort interface (portcls.h)
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:
Inheritance
The IPort interface inherits from the IUnknown interface.
Methods
The IPort interface has these methods.
| IPort::GetDeviceProperty The GetDeviceProperty method provides simplified access to device properties that are contained in the registry for Plug and Play devices. |
| IPort::Init The Init method initializes the port driver. |
| IPort::NewRegistryKey The NewRegistryKey method either opens an existing registry key or creates a new key in the registry. The method creates a registry-key object to represent the key. |
