ACCT(2)                       System Calls Manual                      ACCT(2)

NAME
       acct - turn accounting on or off

SYNOPSIS
       acct(file)
       char *file;

DESCRIPTION
       The system is prepared to write a record in an accounting file for each
       process  as  it  terminates.   This call, with a null-terminated string
       naming an existing file as argument, turns on accounting;  records  for
       each terminating process are appended to file.  An argument of 0 causes
       accounting to be turned off.

       The accounting file format is given in acct(5).

SEE ALSO
       acct(5), sa(8)

DIAGNOSTICS
       On error -1 is returned.  The file must exist and the call may be exer‐
       cised  only  by  the super-user.  It is erroneous to try to turn on ac‐
       counting when it is already on.

BUGS
       No accounting is produced for programs running when a crash occurs.  In
       particular nonterminating programs are never accounted for.
