FreeBSD 7.0 manual page repository

FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

DESCRIPTION

      These interfaces may be used to look up information from the
      audit_control(5) database, which contains various audit-related adminis‐
      trative parameters.
 
      The setac() function resets the database iterator to the beginning of the
      database; see the BUGS section 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 character 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 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.
      The getacdir(), getacmin(), getacflg(), getacna(), getacpol(), and
      au_strtopol() functions return 0 on success, or a negative value on fail‐
      ure, along with error information in errno.
 
      The au_poltostr() function returns a string length of 0 or more on suc‐
      cess, 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.
 

Sections

Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
