Syntax


typedef enum _ELEMENT_TYPE {

  ChangerTransport,
  ChangerSlot,
  ChangerIEPort,
  ChangerDrive,
  ChangerDoor,
  ChangerKeypad
} ELEMENT_TYPE, *PELEMENT_TYPE;

Constants

AllElements

All elements of a changer, including its robotic transport, drives, slots, and insert/eject ports. This value is valid only with IOCTL_CHANGER_GET_ELEMENT_STATUS or IOCTL_CHANGER_INITIALIZE_ELEMENT_STATUS.

ChangerTransport

Robotic transport element, which is used to move media between insert/eject ports, slots, and drives.

ChangerSlot

Storage element, which is a slot in the changer in which media is stored when not mounted in a drive.

ChangerIEPort

Insert/eject port, which is a single- or multiple-cartridge access port in some changers. An element is an insert/eject port only if it is possible to move a piece of media from a slot to the insert/eject port.

ChangerDrive

Data transfer element where data can be read from and written to media.

ChangerDoor

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 is an element of this type. This value is valid only with IOCTL_CHANGER_SET_ACCESS.

ChangerKeypad

Keypad or other input control on the front panel of a changer. This value is valid only with IOCTL_CHANGER_SET_ACCESS.
