Return Value
All I_IrmPolicyInfo Class methods return HRESULT values. A positive OK value indicates that the operation was successful. A negative return value indicates that the function did not succeed.
In general, if an I_IrmPolicyInfo Class method fails, the protector will not be able to recover from the error and will fail as well.
Remarks
This method enables the I_IrmProtector.HrProtect Method method of an autonomous Information Rights Management (IRM) protector to determine the rights that the user has to the requested file.
Windows SharePoint Services determines the access privileges to grant a user based on the access control list (ACL) entry of that user. The rights mask that is passed to the HrGetRightsMask method is not a literal list of ACL permissions, but rather a mapping of ACL permissions to IRM rights. For more information, see Information Rights Management in Windows SharePoint Services Overview.
The I_IrmProtector.HrProtect Method method should not store the rights mask in the rights-managed file. Rather, it should construct an issuance license, or analogous construct for third-party rights management platforms, that lets an IRM-aware client application know what rights to enforce on the file. The rights that are granted should be associated with the user who is requesting the file.
For more information about integrated and autonomous protectors, see Custom IRM Protectors.
