DRM_MSG_ACQUIRE_LICENSE message

[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 DRM_MSG_ACQUIRE_LICENSE message is sent to the custom callback function in response to the DRMAcquireLicense function being called with a license storage session handle.

Parameters

hr

The result of the action being monitored. The contents of the pvParam parameter is dependent on the value of this parameter. This can be one of the following values.

S_DRM_CONNECTING (NULL)

A connection has not yet occurred.

S_DRM_CONNECTED (NULL)

The system has connected to a server.

S_DRM_COMPLETED (NULL)

The operation is complete.

S_DRM_INPROGRESS (A pointer to a DWORD value that contains an integer that represents the progress of the current request, from zero to 100.)

S_DRM_REQUEST_PREPARED (A pointer to a DRM_LICENSE_ACQ_DATA structure that lists license acquisition information for a nonsilent license request.)

This is only returned when DRMAcquireLicense was called by using the DRM_AL_NONSILENT flag. Nonsilent license acquisition is supported only in Rights Management Services client 1.0.

pvParam

The contents of this parameter is dependent on the value in the hr parameter. For more information, see the hr parameter description.

pvContext

An application-defined value, such as a pointer to a callback function, a pointer to an event handle, or other value.

Return value

If the callback function succeeds, the function returns S_OK.

If the callback function fails, it returns an HRESULT error code.

Remarks

The DRMAcquireLicense function is an asynchronous function that will return before this message is sent to the callback function. It is the application's responsibility to ensure that this synchronization is properly handled.
