Class Name:

|
CRmsPartition
|

|
|

Class Description:
|
|||
|
|
|
|||
|
|
A CRmsPartition represents a partition on a tape or a single side of
|
|||
|
|
a unit of optical media. This object keeps on-media identification
|
|||
|
|
information, and various statistics about the Partition including:
|
|||
|
|
capacity, free space, number of physical mounts issued for the
|
|||
|
|
particular Partition, and the amount of data read or written for the
|
|||
|
|
Partition.
