logout -- remove an entry from the utmp file

logout(const char *line);
The function logout() 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.
Logout() returns 1 if the slot described by line has been found and
updated, 0 otherwise.
login(3), utmp(5), wtmp(5)
The calling interface of logout() is inconsistent with that of login(3).
