NAME
     acct - execution accounting file

SYNOPSIS
     #include <sys/types.h>
     #include <sys/acct.h>

DESCRIPTION
     _A_c_c_t(2) causes entries to be made into an accounting file
     for each process that terminates.  The accounting file is a
     sequence of entries whose layout, as defined by the include
     file is:

     /*
      * Accounting structures;
      * these use a comp_t type which is a 3 bits base 8
      * exponent, 13 bit fraction ``floating point'' number.
      */

     struct  acct
     {
             char    ac_comm[10]; /* Accounting command name */
             comp_t  ac_utime;    /* Accounting user time */
             comp_t  ac_stime;    /* Accounting system time */
             comp_t  ac_etime;    /* Accounting elapsed time */
             time_t  ac_btime;    /* Beginning time */
             short   ac_uid;      /* Accounting user ID */
             short   ac_gid;      /* Accounting group ID */
             short   ac_mem;      /* average memory usage */
             comp_t  ac_io;       /* number of disk IO blocks */
             dev_t   ac_tty;      /* control typewriter */
             char    ac_flag;     /* Accounting flag */

     If the process does an _e_x_e_c_v_e(2), the first 10 characters of
     the filename appear in _a_c__c_o_m_m. The accounting flag contains
     bits indicating whether _e_x_e_c_v_e(2) was ever accomplished, and
     whether the process ever had super-user privileges.
