PARTITION_INFORMATION structure

Contains information about a disk partition.

Note PARTITION_INFORMATION has been superseded by the PARTITION_INFORMATION_EX structure.

Syntax


typedef struct _PARTITION_INFORMATION {
  LARGE_INTEGER StartingOffset;
  LARGE_INTEGER PartitionLength;
  DWORD         HiddenSectors;
  DWORD         PartitionNumber;
  BYTE          PartitionType;
  BOOLEAN       BootIndicator;
  BOOLEAN       RecognizedPartition;
  BOOLEAN       RewritePartition;
} PARTITION_INFORMATION, *PPARTITION_INFORMATION;

Members

StartingOffset: The starting offset of the partition.
PartitionLength: The length of the partition, in bytes.
HiddenSectors: The number of hidden sectors in the partition.
PartitionNumber: The number of the partition (1-based).
PartitionType: The type of partition. For a list of values, see Disk Partition Types.
BootIndicator: If this member is TRUE, the partition is bootable.
RecognizedPartition: If this member is TRUE, the partition is of a recognized type.
RewritePartition: If this member is TRUE, the partition information has changed. When you change a partition (with IOCTL_DISK_SET_DRIVE_LAYOUT), the system uses this member to determine which partitions have changed and need their information rewritten.

Remarks

If the partition is on a disk formatted as type master boot record (MBR), partition size totals are limited. For more information, see the Remarks section of IOCTL_DISK_SET_DRIVE_LAYOUT.
