NAME
logout —
remove an entry from the utmp
file
LIBRARY
library “libutil”
SYNOPSIS
#include
<sys/types.h>
#include <libutil.h>
int
logout(const
char *line);
DESCRIPTION
The functionlogout()
searches the utmp(5) file for the slot described by
line (usually a tty name). If such a slot could be
found, it will be updated with a record where the
name and
host fields
are empty, and the time stamp field is updated to the current time.
RETURN VALUES
Logout() returns 1 if the slot described
by line has been found and updated, 0 otherwise.

BUGS
The calling interface of logout() is
inconsistent with that of
login(3).
