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
62The
63.Fn getauclassent
64function
65will return the next class found in the
66.Xr audit_class 5
67database, or the first if the function has not yet been called.
68.Dv NULL
69will be returned if no further records are available.
70.Pp
71The
72.Fn getauclassnam
73function
74looks up a class by name.
75.Dv NULL
76will be returned if no matching class can be found.
77.Pp
78The
79.Fn setauclass
80function
81resets the iterator through the
82.Xr audit_class 5
83database, causing the next call to
84.Fn getauclassent
85to start again from the beginning of the file.
86.Pp
87The
88.Fn endauclass
89function
90closes the
91.Xr audit_class 5
92database, if open.

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 AUTHORS
102.An -nosplit
103This software was created by
104.An Robert Watson ,
105.An Wayne Salamon ,
106and
107.An Suresh Krishnaswamy
108for McAfee Research, the security research division of McAfee,
109Inc., under contract to Apple Computer, Inc.
110.Pp
111The Basic Security Module (BSM) interface to audit records and audit event
112stream format were defined by Sun Microsystems.
113.Sh BUGS
114These routines cannot currently distinguish between an entry not being found
115and an error accessing the database.
116The implementation should be changed to return an error via
117.Va errno
118when
119.Dv NULL
120is returned.
