NAME

 utmpd - utmpx monitoring daemon

SYNOPSIS

 utmpd [-debug]

DESCRIPTION

 

The utmpd daemon monitors the /var/adm/utmpx file. See utmpx(4) (and utmp(4) for historical information).

utmpd receives requests from pututxline(3C) by way of a named pipe. It maintains a table of processes and uses poll(2) on /proc files to detect process termination. When utmpd detects that a process has terminated, it checks that the process has removed its utmpx entry from /var/adm/utmpx. If the process' utmpx entry has not been removed, utmpd removes the entry. By periodically scanning the /var/adm/utmpx file, utmpd also monitors processes that are not in its table.
