DRMGetUnboundLicenseAttributeCount function

[The AD RMS SDK leveraging functionality exposed by the client in Msdrm.dll is available for use in Windows Server 2008, Windows Vista, Windows Server 2008 R2, Windows 7, Windows Server 2012, and Windows 8. It may be altered or unavailable in subsequent versions. Instead, use Active Directory Rights Management Services SDK 2.1, which leverages functionality exposed by the client in Msipc.dll.]

The DRMGetUnboundLicenseAttributeCount function retrieves the number of occurrences of an attribute within an object in an unbound license.

Syntax


HRESULT DRMGetUnboundLicenseAttributeCount(
  _In_  DRMQUERYHANDLE hQueryRoot,
  _In_  PWSTR          wszAttributeType,
  _Out_ UINT           *pcAttributes
);

Parameters

hQueryRoot [in]

A handle to a license or an object in the license, created using DRMGetUnboundLicenseObject or DRMParseUnboundLicense.

wszAttributeType [in]

Name of the attribute to retrieve.

pcAttributes [out]

Count of attribute occurrences one level down within the specified branch.

Return value

If the function succeeds, the function returns S_OK.

If the function fails, it returns an HRESULT value that indicates the error. Possible values include, but are not limited to, those in the following table. For a list of common error codes, see Common HRESULT Values.

Return codeDescription
E_DRM_NO_MORE_DATA

No license or certificate exists at the specified index.

 

Remarks

Certain attributes, such as maximum count, may appear more than once in a branch of a license. This method returns a count of these occurrences, so that an application can iterate through them or access a particular one. This query will search only at the level immediately below the passed in object. So, for example, if the root license handle is passed in and the attribute to find is g_wszQUERY_SKUVALUE, the query will find nothing because the SKUVALUE appears at the second level or deeper (counting the license root as level 0).
