NAME
login, logout, logwtmp - login utility functions
LIBRARY
System Utilities Library (libutil, -lutil)
SYNOPSIS
#include <util.h>
void
login(struct utmp *ut);
int
logout(const char *line);
void
logwtmp(const char *line, const char *name, const char *host);
DESCRIPTION
The 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.
RETURN VALUES
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.
