acct

NAME

       acct - switch process accounting on or off

SYNOPSIS

       #include <unistd.h>

       int acct(const char *filename);

DESCRIPTION

       WARNING:  Since  this  function  is  not implemented as of
       Linux 0.99.11, it will always return -1 and set  errno  to
       ENOSYS.  If acctkit is installed the function performs 'as
       advertised'.

       When called with the name of an existing file as argument,
       accounting is turned on, records for each terminating pro-
       cess are appended to filename as it terminates.  An  argu-
       ment of NULL causes accounting to be turned off.

RETURN VALUE

       On  success,  zero is returned.  On error, -1 is returned,
       and errno is set appropriately.

NOTES

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