- ldev
32-bit signed integer by value (required)
Passes one of the following:
The logical device number (ldev) of the optical drive which contains
mounted media for which information is to be retrieved.
The logical device number of the autochanger for the
magneto-optical device for which information is to be retrieved.
- itemnum_array
32-bit signed integer array by reference (required)
An array of integers where each element is an item number indicating
the magneto-optical device
system information to be returned to a data structure pointed to
in the corresponding element in item_array.
If n item numbers are being requested,
element n+1 must be a zero to indicate the end of the
element list.
- item_array
64-bit address array by reference (required)
An array where each element is a 64-bit address pointing to a
data structure where information is to be returned.
Information and its required data type are
defined by the item number passed in the corresponding element
in itemnum_array.
Array type: globalanyptr (Refer to Appendix B.)
- itemstatus_array
record array by reference (required)
An array where each element returns the status of the operation
performed in the corresponding element in item_array. A zero
indicates a successful operation. A negative value indicates
an error condition. A positive value indicates a warning.
Array type: status_type (Refer to Appendix B.)
- pin
32-bit signed integer by reference (optional)

is to be retrieved.
This is used for
verification of ownership for an optical drive.
If 0 is passed, the pin of the calling process is used.
Default: 0
- user_id
32-bit signed integer by value (optional)
