NAME
acct - switch process accounting on or off
SYNOPSIS
#include <unistd.h> I int acct(const char * filename );
DESCRIPTION
When called with the name of an existing file as argument, accounting is
turned on, records for each terminating process are appended to
filename as it terminates.
An argument 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.
