AU_CONTROL(3)            BSD Library Functions Manual            AU_CONTROL(3)

NAME
     setac, endac, getacdir, getacmin, getacexpire, getacfilesz, getacflg, getacna, getacpol, au_poltostr,
     au_strtopol -- look up information from the audit_control database

LIBRARY
     Basic Security Module Library (libbsm, -lbsm)

SYNOPSIS
     #include <bsm/libbsm.h>

     void
     setac(void);

     void
     endac(void);

     int
     getacdir(char *name, int len);

     int
     getacmin(int *min_val);

     int
     getacexpire(int *andflg, time_t *age, size_t *size);

     int
     getacfilesz(size_t *size_val);

     int
     getacflg(char *auditstr, int len);

     int
     getacna(char *auditstr, int len);

     int
     getacpol(char *auditstr, size_t len);

     ssize_t
     au_poltostr(int policy, size_t maxsize, char *buf);

     int
     au_strtopol(const char *polstr, int *policy);

DESCRIPTION
     These interfaces may be used to look up information from the audit_control(5) database, which contains
     various audit-related administrative parameters.

     The setac() function resets the database iterator to the beginning of the database; see the BUGS sec-tion section
     tion for more information.

     The endac() function closes the audit_control(5) database.

     The getacdir() function returns the name of the directory where log data is stored via the passed char-acter character
     acter buffer name of length len.

     The getacmin() function returns the minimum free disk space for the audit log target file system via
     the passed min_val variable.

     The getacexpire() function returns the audit trail file expiration parameters in the passed int buffer
     andflg, time_t buffer age and size_t buffer size.  If the parameter is not specified in the
     audit_control(5) file it is set to zero.

     The getacfilesz() function returns the audit trail rotation size in the passed size_t buffer size_val.

     The getacflg() function returns the audit system flags via the the passed character buffer auditstr of
     length len.

     The getacna() function returns the non-attributable flags via the passed character buffer auditstr of
     length len.

     The getacpol() function returns the audit policy flags via the passed character buffer auditstr of
     length len.

     The au_poltostr() function converts a numeric audit policy mask, policy, to a string in the passed
     character buffer buf of lenth maxsize.

     The au_strtopol() function converts an audit policy flags string, polstr, to a numeric audit policy
     mask returned via policy.

RETURN VALULES
     The getacdir(), getacmin(), getacexpire(), getacflg(), getacna(), getacpol(), and au_strtopol() func-tions functions
     tions return 0 on success, or a negative value on failure, along with error information in errno.

     The au_poltostr() function returns a string length of 0 or more on success, or a negative value on if
     there is a failure.

     Functions that return a string value will return a failure if there is insufficient room in the passed
     character buffer for the full string.

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.

BUGS
     There is no reason for the setac() interface to be exposed as part of the public API, as it is called
     implicitly by other access functions and iteration is not supported.

     These interfaces inconsistently return various negative values depending on the failure mode, and do
     not always set errno on failure.
