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

89.Sh AUTHORS
90This software was created by Robert Watson, Wayne Salamon, and Suresh
91Krishnaswamy for McAfee Research, the security research division of McAfee,
92Inc., under contract to Apple Computer, Inc.
93.Pp
94The Basic Security Module (BSM) interface to audit records and audit event
95stream format were defined by Sun Microsystems.
96.Sh HISTORY
97The OpenBSM implementation was created by McAfee Research, the security
98division of McAfee Inc., under contract to Apple Computer, Inc., in 2004.
99It was subsequently adopted by the TrustedBSD Project as the foundation for
100the OpenBSM distribution.
101.Sh BUGS
102These routines cannot currently distinguish between an entry not being found
103and an error accessing the database.
104The implementation should be changed to return an error via
105.Va errno
106when
107.Dv NULL
108is returned.
