.Sh SYNOPSIS
|
||
|

.In unistd.h
|
||
|
|
.Ft int
|
||
|
|
.Fn acct "const char *file"
|
||
|
|
.Sh DESCRIPTION
|
||
|
|
The
|
||
|
|
.Fn acct
|
||
|
|
call enables or disables the collection of system accounting records.
|
||
|
|
If
|
||
|
|
.Fa file
|
||
|
|
is
|
||
|
|
.Dv NULL ,
|
||
|
|
accounting is disabled.
|
||
|
|
If
|
||
|
|
.Fa file
|
||
|
|
is an existing, NUL-terminated, pathname, record collection is enabled,
|
||
|
|
and for every process initiated which terminates under normal
|
||
|
|
conditions an accounting record is appended to
|
||
|
|
.Fa file .
|
||
|
|
Abnormal conditions of termination are reboots or other fatal system problems.
|
||
|
|
Records for processes which never terminate can not be
|
||
|
|
produced by
|
||
|
|
.Fn acct .
|
||
|
|
.Pp
|
||
|
|
For more information on the record structure used by
|
||
|
|
.Fn acct ,
|
||
|
|
see
|
||
|
|
.Pa /usr/include/sys/acct.h
|
||
|
|
and
|
||
|
|
.Xr acct 5 .
|
||
|
|
.Pp
|
||
|
|
This call is permitted only to the super-user.
|
||
|
|
.Sh NOTES
|
||
|
|
Accounting is automatically disabled when the file system the
|
||
|
|
accounting file resides on runs out of space; it is enabled when
|
||
|
|
space once again becomes available.
|
||
|
|
For this purpose,
|
||
|
|
.Fn acct
|
||
|
|
creates a kernel thread called
|
||
|
|
.Dq acctwatch .
|
||
|
|
.Sh RETURN VALUES
|
||
|
|
On success, zero is returned.
|
||
|
|
Otherwise, \-1 is returned and
|
||
|
|
.Va errno
|
||
|
|
is set to indicate the error.
|
||
|
|
