The TAPE_GET_POSITION structure describes the position of the tape.
typedef struct _TAPE_GET_POSITION { // tgpos
ULONG Type;
ULONG Partition;
ULONG OffsetLow;
ULONG OffsetHigh;
} TAPE_GET_POSITION;
Members
Type
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.
