Retrieves handles to volumes in the disk set. The third parameter VixVolumeHandle can be a volume handle or an array of volume handles. If you pass an array this function returns the volume handle for the first volume only. If you pass a pointer (such as VixVolumeHandle *volumeHandles) it returns all the volume handles.
