IKsPropertySet
This interface is used to get information about extended properties of sound devices and to manipulate those properties.
You can obtain a pointer to an IKsPropertySet interface by calling the QueryInterface method of an existing interface on a DirectSoundBuffer object. For more information, see Property Sets.
The following table shows the IKsPropertySet methods.
| Method | Description |
|---|---|
| IKsPropertySet::Get | Retrieves the current value of a property. |
| IKsPropertySet::QuerySupport | Determines whether a property set is supported by the object. |
| IKsPropertySet::Set | Sets the current value of a property. |
Like all COM interfaces, the IKsPropertySet interface also inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:
| IUnknown | AddRef |
| QueryInterface | |
| Release |
The LPKSPROPERTYSET type is defined as a pointer to an IKsPropertySet interface, as shown in the following code example.
typedef struct IKsPropertySet *LPKSPROPERTYSET;
