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 combining 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.
