31# event number:event name:event description:event classes (comma separated)
32#
33# Used to map audit events to audit classes for preselection and post-selection.
34# Used by TCB programs that write audit records to preselect audit events
35#     based on event to class mappings.
36#
37# NOTE: several events are obsolete but must continue to be defined here for
38# compatibility reasons. Obsolete events are defined in the "no" (invalid)
39# class to indicate they will not be generated.  Other events in the "no"
40# class which are not obsolete (but are in this class for other reasons),
41# are individually noted with a comment for explanation.
42#
43# System Adminstrators: Do NOT modify or add events with an event number less
44#   than 32768. These are reserved by the system.
45#
46#     0		Reserved as an invalid event number.
47#     1 - 2047	Reserved for the Solaris Kernel events.
48#  2048 - 32767	Reserved for the Solaris TCB programs.
49# 32768 - 65535	Available for third party TCB applications.
