STORAGE_DEVICE_ID_DESCRIPTOR structure (ntddstor.h)
The STORAGE_DEVICE_ID_DESCRIPTOR structure is used in conjunction with the IOCTL_STORAGE_QUERY_PROPERTY request to retrieve the device ID descriptor data for a device.
Syntax
typedef struct _STORAGE_DEVICE_ID_DESCRIPTOR {
ULONG Version;
ULONG Size;
ULONG NumberOfIdentifiers;
UCHAR Identifiers[1];
} STORAGE_DEVICE_ID_DESCRIPTOR, *PSTORAGE_DEVICE_ID_DESCRIPTOR;
Members
Version
Indicates the version of the descriptor.
Size
Indicates the size in bytes of the descriptor.
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 descriptor consists of an array of device IDs taken from the SCSI-3 vital product page data that was retrieved during discovery.
