AU_USER(3)               BSD Library Functions Manual               AU_USER(3)

NAME
     setauuser, endauuser, getauuserent, getauuserent_r, getauusernam, getauusernam_r, au_user_mask,
     getfauditflags -- look up information from the audit_user database

LIBRARY
     Basic Security Module Library (libbsm, -lbsm)

SYNOPSIS
     #include <bsm/libbsm.h>

     void
     setauuser(void);

     void
     endauuser(void);

     struct au_user_ent *
     getauuserent(void);

     struct au_user_ent *
     getauuserent_r(struct au_user_ent *u);

     struct au_user_ent *
     getauusernam(const char *name);

     struct au_user_ent *
     getauusernam_r(struct au_user_ent *u, const char *name);

     int
     au_user_mask(char *username, au_mask_t *mask_p);

     int
     getfauditflags(au_mask_t *usremask, au_mask_t *usrdmask, au_mask_t *lastmask);

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 proper-ties properties
     ties 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.
