MM_VOLUME_RETURN_PARTITION_MAPPING
Requests the file system application to return all of the volume segments that it recognizes on the specified logical partition.
Parameters to MM_ObjectControl for this operation are as follows:
The following table lists return values and descriptions.
0x00000000 |
MM_OK |
0x0000020B |
MM_BUFFER_TOO_SMALL The number of provided array elements was not enough to receive all of the LogicalPartitionMappingElementDef structures. If this return value is returned, the file system application will place a value in the numberOfElements field of the LogicalPartitionMappingInfo structure indicating the actual number of segments that make up the volume. The calling application then knows how many array elements are required and can retry this operation with the proper adjustments made. |
This information is returned in a LogicalPartitionMappingInfo structure which the application must allocate prior to calling this operation.
The LogicalPartitionMappingElementDef structure describes the volume segment.
