SET_PARTITION_INFORMATION structure (ntdddisk.h)

SET_PARTITION_INFORMATION is used with IOCTL_DISK_SET_PARTITION_INFO to change the partition type of a specified Master Boot Record (MBR) disk partition.

Syntax

typedef struct _SET_PARTITION_INFORMATION {
  UCHAR PartitionType;
} SET_PARTITION_INFORMATION, *PSET_PARTITION_INFORMATION;

Members

PartitionType

Indicates the partition type. IOCTL_DISK_SET_PARTITION_INFO uses this value to set the partition type. See PARTITION_INFORMATION for a list of system-defined GPT partition types.

Remarks

The single byte unsigned value, PartitionType, contained in this structure defines a traditional AT Master Boot Record style of partition and cannot be used to define an Extensible Firmware Interface partition (also known as a GUID Partition Table partition). GPT partitions use a GUID to indicate the partition type.

Requirements

   
Header ntdddisk.h (include Ntdddisk.h)
