<H2>DESCRIPTION</H2>
|
|
|
|
The
|
|
<B>acct</B>()
|
|
|
|
system call enables or disables process accounting.
|
|
If called with the name of an existing file as its argument,
|
|
accounting is turned on,
|
|
and records for each terminating process are appended to
|
|
<I>filename</I>
|
|
|
|
as it terminates.
|
|
An argument of NULL causes accounting to be turned off.
|
|
<A NAME="lbAE"> </A>
|
|
<H2>RETURN VALUE</H2>
|
|
|
|
On success, zero is returned.
|
|
On error, -1 is returned, and
|
|
<I>errno</I>
|
|
|
|
is set appropriately.

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