53.Sh DESCRIPTION
54These interfaces may be used to look up information from the
55.Xr audit_class 5
56database, which describes audit event classes.
57Audit event classes are described by
58.Vt "struct au_class_ent" .
59.Pp
60The
61.Fn getauclassent
62function
63will return the next class found in the
64.Xr audit_class 5
65database, or the first if the function has not yet been called.
66.Dv NULL
67will be returned if no further records are available.
68.Pp
69The
70.Fn getauclassnam
71function
72looks up a class by name.
73.Dv NULL
74will be returned if no matching class can be found.
75.Pp
76The
77.Fn setauclass
78function
79resets the iterator through the
80.Xr audit_class 5
81database, causing the next call to
82.Fn getauclassent
83to start again from the beginning of the file.
84.Pp
85The
86.Fn endauclass
87function
88closes the
89.Xr audit_class 5
90database, if open.

94.Sh HISTORY
95The OpenBSM implementation was created by McAfee Research, the security
96division of McAfee Inc., under contract to Apple Computer, Inc., in 2004.
97It was subsequently adopted by the TrustedBSD Project as the foundation for
98the OpenBSM distribution.
99.Sh AUTHORS
100.An -nosplit
101This software was created by
102.An Robert Watson ,
103.An Wayne Salamon ,
104and
105.An Suresh Krishnaswamy
106for McAfee Research, the security research division of McAfee,
107Inc., under contract to Apple Computer, Inc.
108.Pp
109The Basic Security Module (BSM) interface to audit records and audit event
110stream format were defined by Sun Microsystems.
111.Sh BUGS
112These routines cannot currently distinguish between an entry not being found
113and an error accessing the database.
114The implementation should be changed to return an error via
115.Va errno
116when
117.Dv NULL
118is returned.
