Microsoft DirectX 9.0

IKsPropertySet Interface

The IKsPropertySet interface allows drivers to provide extended capabilities that can be used without API extensions. DirectSound supports this interface for accessing properties of sound drivers.

The IKsPropertySet interface is part of the WDM KS (Win32® driver model kernel streaming) architecture.

Note   The declaration of this interface in Dsound.h is different from that in Ksproxy.h and Strmif.h. If your project includes Ksproxy.h or Strmif.h but you wish to use the DirectSound implementation, be sure to include Dsound.h first. Failing to do so may cause your application to stop responding when a method of IKsPropertySet is called.

To retrieve this interface, call the QueryInterface method of any interface on a DirectSound buffer.

In addition to the methods inherited from IUnknown, the IKsPropertySet interface exposes the following methods.

Method Description
Get Retrieves data for an item in a property set.
QuerySupport Ascertains whether a property in a property set is supported on the port or device.
Set Sets the value of a property in a property set.
