NAME
acct - execution accounting file
SYNOPSIS
#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:
/* acct.h 4.1 11/9/80*/
/*
* Accounting structures
*/
typedef unsigned short comp_t; /* "floating pt": 3 bits base 8 exp, 13 bits fraction */
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 */
};
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 */
If the process does an _e_x_e_c(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(2) was ever accomplished, and
whether the process ever had super-user privileges.
