66.Sh DESCRIPTION
67These interfaces may be used to look up information from the
68.Xr audit_event 5
69database, which describes audit events.
70Entries in the database are described by
71.Vt "struct au_event_ent"
72entries, which are returned by calls to
73.Fn getauevent ,
74.Fn getauevnam ,
75or
76.Fn getauevnum .
77It is also possible to look up an event number via a call to
78.Fn getauevnonam .
79.Pp
80The
81.Fn setauevent
82function
83resets the database access session for
84.Xr audit_event 5 ,
85so that the next call to
86.Fn getauevent
87will start with the first entry in the database.
88.Pp
89The
90.Fn endauevent
91function
92closes the
93.Xr audit_event 5
94database session.
95.Pp
96The
97.Fn getauevent
98function
99returns a reference to the next entry in the
100.Xr audit_event 5
101database.
102.Pp
103The
104.Fn getauevnam
105function
106returns a reference to the entry in the
107.Xr audit_event 5
108database with a name of
109.Fa name .
110.Pp
111.Fn getauevnum
112returns a reference to the entry in the
113.Xr audit_event 5
114database with an event number of
115.Fa event_number .
116.Pp
117The
118.Fn getauevnonam
119function
120returns a reference to an audit event number using the
121.Xr audit_event 5
122database.

145.Sh HISTORY
146The OpenBSM implementation was created by McAfee Research, the security
147division of McAfee Inc., under contract to Apple Computer, Inc., in 2004.
148It was subsequently adopted by the TrustedBSD Project as the foundation for
149the OpenBSM distribution.

152This software was created by
153.An Robert Watson ,
154.An Wayne Salamon ,
155and
156.An Suresh Krishnaswamy
157for McAfee Research, the security research division of McAfee,
158Inc., under contract to Apple Computer, Inc.
159.Pp
160The Basic Security Module (BSM) interface to audit records and audit event
161stream format were defined by Sun Microsystems.
162.Sh BUGS
163The
164.Va errno
165variable
166is not always properly set following a failure.
167.Pp
168These routines are thread-safe, but not re-entrant, so simultaneous or
169interleaved use of these functions will affect the iterator.
