NAME
     acct - execution accounting file

SYNOPSIS
     #include <sys/acct.h>

DESCRIPTION
     The acct(2) system call arranges for entries to be made in
     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:

     typedef   ushort comp_t;      /* "floating point" */
           /* 13-bit fraction, 3-bit exponent  */

     struct   acct
     {
        char    ac_flag;      /* Accounting flag */
        char    ac_stat;      /* Exit status */
        ushort   ac_uid;      /* Accounting user ID */
        ushort   ac_gid;      /* Accounting group ID */
        dev_t    ac_tty;      /* control typewriter */
        time_t   ac_btime;    /* Beginning time */
        comp_t   ac_utime;    /* acctng user time in clock ticks */
        comp_t   ac_stime;    /* acctng system time in clock ticks */
        comp_t   ac_etime;    /* acctng elapsed time in clock ticks */
        comp_t   ac_mem;      /* memory usage */
        comp_t   ac_io;       /* chars transferred */
        comp_t   ac_rw;       /* blocks read or written */
        char    ac_comm[8];   /* command name */
     };

     extern   struct   acct   acctbuf;
     extern   struct   inode   *acctp;    /* inode of accounting file */

     #define   AFORK   01      /* has executed fork, but no exec */
     #define   ASU     02      /* used super-user privileges */
     #define   ACORE   0010    /* dumped core */
     #define   AXSIG   0020    /* killed by a signal */
     #define   ACCTF   0300    /* record type: 00 = acct */

     #endif   _SYS_ACCT_

     If the process was created by an execve(2), the first 10
     characters of the filename appear in ac_comm. In ac_flag,
     the AFORK flag is turned on by each fork(2) and turned off
     by an exec(2), the ASU flag is set when a command is exe-
     cuted by the super-user, the ACORE flag is set when a com-
     mand is terminated with the generation of a core file, and
     the AXSIG flag is set when a command is terminated with a
     signal.
