PARTITION_INFORMATION info  Overview  Group

The PARTITION_INFORMATION structure provides information about a disk partition.

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

Specifies the starting offset of the partition.

PartitionLength

Specifies the length of the partition.

HiddenSectors

Specifies the number of hidden sectors in the partition.

PartitionNumber

Specifies the number of the partition (1-based).

PartitionType

BootIndicator

Specifies whether the partition is bootable.

RecognizedPartition

Specifies whether the partition is recognized.

RewritePartition

Specifies whether 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

The DeviceIoControl function receives a PARTITION_INFORMATION structure in response to an IOCTL_DISK_GET_PARTITION_INFO or IOCTL_DISK_GET_DRIVE_LAYOUT device input and output control (IOCTL) operation. The DeviceIoControl function uses a PARTITION_INFORMATION structure as input to an IOCTL_DISK_SET_DRIVE_LAYOUT device IOCTL operation.
