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.

OPTIONS
