#include <utmpx.h>
The <utmpx.h>
header defines the structures and functions for logging user. Currently
logged in users are tracked in /var/run/utmpx, a
list of all logins and logouts, as well as all shutdowns, reboots and date
changes, is kept in /var/log/wtmpx, and the last
login of each user is noted in
/var/log/lastlogx.
The interface to the utmpx
file is
described in
getutxent(3).
The wtmpx
file can grow rapidly on busy
systems, and is normally rotated with
newsyslog(8).
In the event of a date change, a shutdown, or a reboot, the
following items are logged in the wtmpx
file:
date
|
’ indicates the time
prior to the change, and the character
‘{
’ indicates the new time.reboot
shutdown
~
’ is placed in the field
ut_line, and reboot
or
shutdown
in the field
ut_name (see
shutdown(8) and
reboot(8)), using
logwtmpx(3).utmpx
