DESCRIPTION
These interfaces may be used to look up information from the
audit_user(5) database, which describes per-user audit configuration.
Audit user entries are described by a au_user_ent, which stores the
user's name in au_name, events to always audit in au_always, and events
never to audit au_never.
The getauuserent() function returns the next user found in the
audit_user(5) database, or the first if the function has not yet been
called. NULL will be returned if no further records are available.
The getauusernam() function looks up a user by name. NULL will be
returned if no matching class can be found.
The setauuser() function resets the iterator through the audit_user(5)
database, causing the next call to getauuserent() to start again from the
beginning of the file.
The endauuser() function closes the audit_user(5) database, if open.
The au_user_mask() function calculates a new session audit mask to be
returned via mask_p for the user identified by username. If the user
audit configuration is not found, the default system audit properties
returned by getacflg(3) are used. The resulting mask may be set via a
call to setaudit(2) or related variants.
The getfauditflags() function generates a new process audit state by com-
bining the audit masks passed as parameters with the system audit masks.

HISTORY
The OpenBSM implementation was created by McAfee Research, the security
division of McAfee Inc., under contract to Apple Computer, Inc., in 2004.
It was subsequently adopted by the TrustedBSD Project as the foundation
for the OpenBSM distribution.
AUTHORS
This software was created by Robert Watson, Wayne Salamon, and Suresh
Krishnaswamy for McAfee Research, the security research division of
McAfee, Inc., under contract to Apple Computer, Inc.
The Basic Security Module (BSM) interface to audit records and audit
event stream format were defined by Sun Microsystems.
BUGS
These routines cannot currently distinguish between an entry not being
found and an error accessing the database. The implementation should be
changed to return an error via errno when NULL is returned.
