NetBSD 6.1.5 - man page for utmpx (netbsd section 5)

UTMPX(5)			     BSD File Formats Manual				 UTMPX(5)

NAME
     utmpx, wtmpx, lastlogx -- user accounting database

SYNOPSIS
     #include <utmpx.h>

DESCRIPTION
     In contrast to utmp and wtmp, the extended databases in utmpx and wtmpx reserve more space
     for logging hostnames, and also information on a process' ID, termination signal and exit
     status.

     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        The system time has been manually or automatically updated by date(1).
		       The command name date is recorded in the field ut_name.	In the field
		       ut_line, the character '|' indicates the time prior to the change, and the
		       character '{' indicates the new time.
	   reboot
	   shutdown    A system reboot or shutdown has been initiated.	The character '~' 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).

FILES
     /var/run/utmpx	The utmpx file.
     /var/log/wtmpx	The wtmpx file.
     /var/log/lastlogx	The lastlogx file.
