[MS-VDS]: Virtual Disk Service (VDS) Protocol Specification

Return Values: The method MUST return zero or a non-error HRESULT (as specified in [MS-ERREF]) to indicate success, or return an implementation-specific nonzero error code toindicate failure. For the HRESULT values predefined by the Virtual Disk Service RemoteProtocol, see section 2.2.3.When the server receives this message, it MUST validate the following parameter:•Verify that ppPack is not NULL.The server MUST perform the following:•Create a new pack object that implements the IVdsPack interface and assign it a uniqueVDS_OBJECT_ID.•Set the provider pointer of the disk pack object to this provider object.•Add the pack object to the list of storage management objects.•For each callback object that is registered in the list of callback objects, call theIVdsAdviseSink::OnNotify (Opnum 3) method of the callback object with aVDS_NOTIFICATION structure that has the following attributes:•objectType member is VDS_NTT_PACK.•Pack member is a VDS_PACK_NOTIFICATION with the following attributes:•ulEvent is VDS_NF_PACK_ARRIVE.•packId is the VDS_OBJECT_ID of the pack object that was added.•Set the pointer that ppPack references to the IVdsPack interface of the pack object.•Return an HRESULT indicating failure or success.3.4.5.2.15 IVdsHwProvider Methods3.4.5.2.15.1 IVdsHwProvider::QuerySubSystems (Opnum 3)The QuerySubSystems method retrieves the subsystems that are managed by the provider.HRESULT QuerySubSystems([out] IEnumVdsObject** ppEnum);ppEnum: A pointer to an IEnumVdsObject interface. If the operation is successfully completed,the pointer receives the IEnumVdsObject interface of the object, which contains anenumeration of subsystem objects in the provider. Callers MUST release the interface whenthey are finished with it.Return Values: The method MUST return zero or a non-error HRESULT (as specified in [MS-ERREF]) to indicate success, or return an implementation-specific nonzero error code toindicate failure. For the HRESULT values predefined by the Virtual Disk Service RemoteProtocol, see section 2.2.3.When the server receives this message, it MUST validate the following parameter:[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011190 / 360
