This is preliminary documentation and subject to change.

This topic documents a feature of the Windows Media Device Manager SDK. We recommend that you migrate your application to use the Windows Portable Devices API. For more information, see the Windows Portable Devices SDK.

Windows Media Device Manager uses IMDSPObject2 to enable more efficient file reading and writing.

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 IMDSPObject, the IMDSPObject2 interface exposes the following methods.

Method Description
ReadOnClearChannel Reads data from the object at the current position without secure authenticated channel (SAC).
WriteOnClearChannel Writes data to the object at the current position without SAC.
