NAME
     audit.log - audit trail file

SYNOPSIS
     #include <bsm/audit.h>

     #include <bsm/audit_record.h>

DESCRIPTION
     audit.log files are the depository for audit records  stored
     locally  or   on  an  audit server.  These files are kept in
     directories named in the  file  audit_control(4).  They  are
     named  to  reflect  the  time they are created and are, when
     possible, renamed to reflect the time  they  are  closed  as
     well. The name takes the form

          yyyymmddhhmmss.not_terminated.hostname


     when open or if the  auditd(1M) terminated ungracefully, and
     the form

          yyyymmddhhmmss.yyyymmddhhmmss.hostname


     when properly closed. yyyy is the year, mm the month, dd day
     in the month, hh hour in the day, mm minute in the hour, and
     ss second in the minute. All fields are of fixed width.

     The audit.log file begins with a standalone  file token  and
     typically  ends  with  one  also.  The beginning  file token
     records the pathname of the previous audit file,  while  the
     ending   file  token  records the pathname of the next audit
     file.   If the file name is NULL the  appropriate  path  was
     unavailable.

     The audit.log  files  contains  audit  records.  Each  audit
     record  is  made  up of audit tokens. Each record contains a
     header token followed by various data tokens.  Depending  on
     the  audit  policy  in  place by  auditon(2), optional other
     tokens such as trailers or sequences may be included.

     The tokens are defined as follows:

     The  file token consists of:

     token ID                1 byte
     seconds of time         4 bytes
     milliseconds of time    4 bytes
     file name length        2 bytes
     file pathname           N bytes + 1 terminating NULL byte
