DRMGetBoundLicenseAttributeCount 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 2.0, which leverages functionality exposed by the client in Msipc.dll.]

The DRMGetBoundLicenseAttributeCount function retrieves the number of occurrences of an attribute in a license.

Syntax


HRESULT DRMGetBoundLicenseAttributeCount(
  _In_   DRMHANDLE hQueryRoot,
  _In_   PWSTR wszAttribute,
  _Out_  UINT *pcAttributes
);

Parameters

hQueryRoot [in]

A handle to a license or license object, from DRMGetBoundLicenseObject or DRMCreateBoundLicense.

wszAttribute [in]

Name of the attribute to count.

pcAttributes [out]

Count of attribute occurrences.

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.

E_DRM_QUERY_REPORTS_NO_RESULTS

The attribute was not found.

 

Remarks

Certain attributes, such as maximum use count, may appear in more than one branch of a license. This method returns a count of these occurrences, so that an application can iterate through them to access a particular one by using DRMGetBoundLicenseAttribute.

The Active Directory Rights Management system exposes an object-oriented interface to the underlying license XrML. This function, along with other DRMGetBoundLicense_xxx functions, allows an application to navigate this structure. For more information, see Querying Licenses.
