NAME
       acct.h, acct - per-process accounting file format

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

DESCRIPTION
       Files  produced as a result of calling acct(2) have records in the form
       defined by <sys/acct.h>, whose contents are:

       typedef ushort_t	 comp_t;   /* pseudo "floating point" representation */
				   /* 3 bit base-8 exponent in the high */
				   /* order bits, and a 13-bit fraction */
				   /* in the low order bits. */

       struct	 acct
       {
	   char	  ac_flag;    /* Accounting flag */
	   char	  ac_stat;    /* Exit status */
	   uid_t  ac_uid;     /* Accounting user ID */
	   gid_t  ac_gid;     /* Accounting group ID */
	   dev_t  ac_tty;     /* control tty */
	   time_t ac_btime;   /* Beginning time */
	   comp_t ac_utime;   /* accounting user time in clock ticks */
	   comp_t ac_stime;   /* accounting system time in clock ticks */
	   comp_t ac_etime;   /* accounting total elapsed time in clock ticks */
	   comp_t ac_mem;     /* memory usage in clicks (pages) */
	   comp_t ac_io;      /* chars transferred by read/write */
	   comp_t ac_rw;      /* number of block reads/writes */
	   char	  ac_comm[8]; /* command name */
       };

       /*
	* Accounting Flags
	*/

       #define AFORK   01    /* has executed fork, but no exec */
       #define ASU     02    /* used super-user privileges */
       #define ACCTF   0300  /* record type */
       #define AEXPND  040   /* Expanded Record Type − default */

       In ac_flag, the AFORK flag is turned on by each fork and turned off  by
       an  exec. The ac_comm field is inherited from the parent process and is
       reset by any exec. Each time the system	charges	 the  process  with  a
       clock  tick,  it also adds to ac_mem the current process size, computed
       as follows:

	      (data size) + (text size) / (number of in-core  processes	 using
	      text)

       The  value of ac_mem/(ac_stime+ac_utime) can be viewed as an approxima‐
       tion to the mean process size, as modified by text sharing.

       The structure tacct, (which  resides  with  the	source	files  of  the
       accounting commands), represents a summary of accounting statistics for
       the user id ta_uid. This structure is used by the  accounting  commands
       to report  statistics based on user id.

       /*
	*  total accounting (for acct period), also for day
	*/
       struct tacct {
	  uid_t		  ta_uid;	/* user id */
	  char		  ta_name[8];	/* login name */
	  float		  ta_cpu[2];	/* cum. cpu time in minutes, */
					/* p/np (prime/non-prime time) */
	  float		  ta_kcore[2];	/* cum. kcore-minutes, p/np */
	  float		  ta_con[2];	/* cum. connect time in minutes, p/np */
	  float		  ta_du;	/* cum. disk usage (blocks)*/
	  long		  ta_pc;	/* count of processes */
	  unsigned short  ta_sc;	/* count of login sessions */
	  unsigned short  ta_dc;	/* count of disk samples */
	  unsigned short  ta_fee;	/* fee for special services */
       };

       The ta_cpu, ta_kcore, and ta_con members contain usage information per‐
       taining to prime time and non-prime time hours.	The first  element  in
       each array represents the time the  resource was used during prime time
       hours.  The second element in   each  array  represents	the  time  the
       resource	 was  used  during  non-prime time hours.  Prime time and non-
       prime time hours may be set in the  holidays file (see holidays(4)).

       The ta_kcore member is a cumulative measure of  the  amount  of	memory
       used   over  the	 accounting period by processes owned by the user with
       uid ta_uid. The amount shown represents	kilobyte  segments  of	memory
       used, per minute.

       The  ta_con member represents the amount of time the user was logged in
       to the system.

FILES
       /etc/acct/holidays      prime/non-prime time table

       fork(2)

NOTES
       The ac_mem value for a short-lived  command  gives  little  information
       about the actual size of the command, because ac_mem may be incremented
       while a different command (for example, the shell) is being executed by
       the process.
