IMDSPStorage4 Interface

The IMDSPStorage4 interface extends IMDSPStorage3 for supporting virtual storages (such as playlists and albums) and metadata.

• Note   Unless the service provider has added the device parameter UseExtendedWmdm with a value of 1, Windows Media Device Manager will not call this interface. See Device Parameters for more information about this.

In addition to the methods inherited from IMDSPStorage3, the IMDSPStorage4 interface exposes the following methods.

Method	Description
CreateStorageWithMetadata	Creates a new storage supporting metadata, and returns a pointer to the IMDSPStorage interface on the newly created storage. The new storage can be created at the same level or can be inserted into the current storage.
FindStorage	Retrieves the storage through its unique identification (ID).
GetParent	Retrieves the parent storage object.
GetReferences	Retrieves references of an association object.
GetSpecifiedMetadata	Retrieves the specified metadata.
SetReferences	Sets references of an association object.
