Control group entry action
Control group entry action
The action the
exit program wants the control group processing program to take relative
to the current control group entries. Possible values are:
0
Continue processing entries but do not call exit program again.
1
Continue processing entries and call exit program after the
next entry is processed.
2
Retry the current entry and call exit program after the entry
is processed.
Note:
The current entry will be retried for
as many times as this value is returned in the control information.
The exit program is responsible for preventing infinite loop conditions
when this value is used repeatedly for the same group of entries.

End control group processing. Do not process subsequent entries.
Perform control group post processing which may include saving media
information, starting subsystems, restarting the system, or other
post processing operations as determined by the control group attributes.
15
End control group processing. Do not process subsequent entries.
Do not perform control group post-processing such as saving
media information, starting subsystems, restarting the system, or
other post processing operations.
