STORAGE_DEVICE_ID_DESCRIPTOR structure (winioctl.h)

Used with the IOCTL_STORAGE_QUERY_PROPERTY control code request to retrieve the device ID descriptor data for a device.

Syntax

typedef struct _STORAGE_DEVICE_ID_DESCRIPTOR {
  DWORD Version;
  DWORD Size;
  DWORD NumberOfIdentifiers;
  BYTE  Identifiers[1];
} STORAGE_DEVICE_ID_DESCRIPTOR, *PSTORAGE_DEVICE_ID_DESCRIPTOR;

Members

Version

Contains the size of this structure, in bytes. The value of this member will change as members are added to the structure.

Size

Specifies the total size of the data returned, in bytes. This may include data that follows this structure.

NumberOfIdentifiers

Contains the number of identifiers reported by the device in the Identifiers array.

Identifiers[1]

Contains a variable-length array of identification descriptors.

Remarks

The device ID descriptor consists of an array of device IDs taken from the SCSI-3 vital product data (VPD) page 0x83 that was retrieved during discovery.
