high-order bit set", as this error is obsolete. Eventually we may want to add code to some of the "optional" filesystems (msdosfs, etc.) that checks for illegal characters. At that time it would be appropriate to reintroduce this error with appropriate text. Perhaps "The pathname contains a character that is not valid for filesystem type".

|
|
.Sh SYNOPSIS
|
|
.Fd #include <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 the argument
|
|
.Fa file
|
|
is a nil pointer, accounting is disabled.
|
|
If
|
|
.Fa file
|
|
is an
|
|
.Em existing
|
|
pathname (null-terminated), 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 ,
|
|

|
|
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.
|
|
.Sh RETURN VALUES
|
|
On error -1 is returned.
|
|
The file must exist and the call may be exercised only by the super-user.
