ELEMENT_TYPE enumeration (ntddchgr.h)

The ELEMENT_TYPE enumeration provides a list of changer element types defined by the SCSI-3 specification.

Syntax

typedef enum _ELEMENT_TYPE {
  AllElements,
  ChangerTransport,
  ChangerSlot,
  ChangerIEPort,
  ChangerDrive,
  ChangerDoor,
  ChangerKeypad,
  ChangerMaxElement
} ELEMENT_TYPE, *PELEMENT_TYPE;

Constants

AllElements Indicates all elements of a changer, including its robotic transport, drives, slots, and IEport. AllElements is valid only in a ChangerGetElementStatus or ChangerInitializeElementStatus call.
ChangerTransport Indicates the changer's robotic transport element, which is used to move media between IEports, slots, and drives.
ChangerSlot Indicates a storage element, which is a slot in the changer in which media is stored when not mounted in a drive.
ChangerIEPort Indicates an import/export element (IEport), which is a single or multiple-cartridge access port in some changers. An element is an IEport only if it is possible to move a piece of media from a slot to the IEport.
ChangerDrive Indicates a data transfer element where data can be read from and written to media.
ChangerDoor Indicates a mechanism that provides access to all media in a changer at one time (as compared to an IEport that provides access to one or more, but not all, media). For example, a large front door or a magazine that contains all media in the changer are elements of this type. ChangerDoor is valid only in a ChangerSetAccess call.
ChangerKeypad Indicates the keypad or other input control on the front panel of a changer. ChangerKeypad is valid only in a ChangerSetAccess call.
ChangerMaxElement Indicates the upper limit of the enumerators in this enumeration.
