Specifies the
type of position. This member must be one of the following values:
|
Value |
Description |
|
TAPE_ABSOLUTE_POSITION |
The
position specified by the OffsetLow and OffsetHigh members is
an absolute number of blocks from the beginning of the partition specified by
the Partition member. |
|
TAPE_LOGICAL_POSITION |
The
position specified by OffsetLow and OffsetHigh is relative to
the current position in the partition specified by Partition. |
Partition
Specifies the
partition to position within. If this member is zero, the current partition is
assumed.
OffsetLow
Specifies the
low-order 32 bits of the block address.
OffsetHigh
Specifies the
high-order 32 bits of the block address. If the high-order 32 bits are not
required, this member should be zero.
