login(), logout(), and
logwtmp() functions operate on the database of current
users in /var/run/utmp and on the logfile
/var/log/wtmp of logins and logouts.
The login() function updates the
/var/run/utmp and
/var/log/wtmp files with user information contained
in ut.
The logout() function removes the entry
from /var/run/utmp corresponding to the device
line.
The logwtmp() function adds an entry to
/var/log/wtmp. Since login()
will add the appropriate entry for /var/log/wtmp
during a login, logwtmp() is usually used for
logouts.
logout() returns non-zero if it was able to find and
delete an entry for line, and zero if there is no entry
for line in /var/run/utmp.
