PARTITION_INFORMATION structure (winioctl.h)
Contains information about a disk partition.
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.
