  19 The \fButmpd\fR daemon monitors the \fB/var/adm/utmpx\fR file. See
  20 \fButmpx\fR(4) (and \fButmp\fR(4) for historical information).
  21 .sp
  22 .LP
  23 \fButmpd\fR receives requests from \fBpututxline\fR(3C) by way of a named pipe.
  24 It maintains a table of processes and uses \fBpoll\fR(2) on \fB/proc\fR files
  25 to detect process termination. When \fButmpd\fR detects that a process has
  26 terminated, it checks that the process has removed its \fButmpx\fR entry from
  27 \fB/var/adm/utmpx\fR. If the process' \fButmpx\fR entry has not been removed,
  28 \fButmpd\fR removes the entry. By periodically scanning the
  29 \fB/var/adm/utmpx\fR file, \fButmpd\fR also monitors processes that are not in
  30 its table.
