IWMDRMReader3::GetInclusionList method (wmsdkidl.h)

[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

[GetInclusionList is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions. Instead, use Microsoft PlayReady. ]

The GetInclusionList method retrieves a list of identifiers specifying approved protection systems.

Syntax

HRESULT GetInclusionList(
  [out] GUID  **ppGuids,
  [out] DWORD *pcGuids
);

Parameters

[out] ppGuids

Address of a variable that receives a pointer to an array of identifiers. The array is allocated by using CoTaskMemAlloc. When finished with the list, release the memory by calling CoTaskMemFree.

[out] pcGuids

Number of elements in the array received by the ppGuids parameter.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Remarks

The license issuer can specify other protection systems to which the encrypted content may be converted. The list of GUIDs retrieved by this method identifies the allowed protection systems. When you enter into a license agreement with Microsoft to get the stub library, you will receive a list of currently supported protection systems and the GUIDs used to identify them.
