.In utmpx.h
|
|
.Sh DESCRIPTION
|
|
In contrast to
|
|
.Pa utmp
|
|
and
|
|
.Pa wtmp ,
|
|
the extended databases in
|
|
.Pa utmpx
|
|
and
|
|
.Pa wtmpx
|
|
reserve more space for logging hostnames, and also
|
|
information on a process' ID, termination signal and exit status.
|
|
.Pp
|
|
The
|
|
.Aq Pa utmpx.h
|
|
header defines the structures and functions for logging user.
|
|
Currently logged in users are tracked in
|
|
.Pa /var/run/utmpx ,
|
|
a list of all logins and logouts, as well as all shutdowns, reboots
|
|
and date changes, is kept in
|
|
.Pa /var/log/wtmpx ,
|
|
and the last login of each user is noted in
|
|
.Pa /var/log/lastlogx .
|
|
.Pp
|
|
The interface to the
|
|
.Nm utmpx
|
|
file is described in
|
|
.Xr getutxent 3 .
|
|
.Pp
|
|
The
|
|
.Nm wtmpx
|
|
file can grow rapidly on busy systems, and is normally rotated with
|
|
.Xr newsyslog 8 .
|
|
.Pp
|
|
In the event of a date change, a shutdown, or a reboot, the following
|
|
items are logged in the

|
|
file:
|
|
.Bl -tag -width shutdownxx -compact -offset indent
|
|
.It Li date
|
|

|
|
the character
