Revocation_Callback.cpp

[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 following example shows a custom callback function that will be called by DRMAcquireLicense during acquisition of the end-user license chain. In this example, a blocking event object is created in Revocation_GetEULChain.cpp prior to calling the DRMAcquireLicense function. DRMAcquireLicense is an asynchronous function that returns control immediately and continues processing on another thread, periodically calling into your callback with status information that you can filter and report back to the user. After the license has been saved in the certificate store, this example processes the S_DRM_COMPLETED value and calls the SetEvent function to unblock the primary process thread.
