STORAGE_DEVICE_ID_DESCRIPTOR structure

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
