ACCT(5)                 GENIX Programmer's Manual                 ACCT(5)



      NAME
           acct - execution accounting file

      SYNOPSIS
           #include <sys/acct.h>

      DESCRIPTION
           Acct(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:

           /*
            * acct.h       1.2            7/14/83
            */

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

           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 */
           };

           #define AFORK   01             /* has executed fork, but no exec */
           #define ASU     02             /* used super-user privileges */

           If the process does an exec(2),  the  first  10  characters  of  the
           filename  appear in ac_comm. The accounting flag contains bits indi-
           cating whether exec(2) was ever accomplished, and whether  the  pro-
           cess ever had super-user privileges.
