CREATE_DISK_GPT structure (winioctl.h)

Contains information used by the IOCTL_DISK_CREATE_DISK control code to initialize GUID partition table (GPT) disks.

Syntax

typedef struct _CREATE_DISK_GPT {
  GUID  DiskId;
  DWORD MaxPartitionCount;
} CREATE_DISK_GPT, *PCREATE_DISK_GPT;

DiskId

The disk identifier (GUID) of the GPT disk to be initialized.

MaxPartitionCount

The maximum number of partitions allowed on the GPT disk to be initialized without repartitioning the disk.

The CREATE_DISK_GPT structure is defined as part of the CREATE_DISK structure.

If a maximum partition count of less than 128 is specified, it will be reset to 128. This is in compliance with the EFI specification.
