LOGOUT(3) BSD Library Functions Manual LOGOUT(3)NAMElogout — remove an entry from the utmp file
System Utilities Library (libutil, -lutil)
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.
The logout() function returns 1 if the slot described by line has been
found and updated, 0 otherwise.
