NAME
     cssd - daemon which invokes and watches the CSs

SYNOPSIS
     /usr/sbin/cssd [ -f filename ]

AVAILABILITY
     SUNWjfpu

DESCRIPTION
     cssd is the command which invokes and watches CS (  cs00(1M)
     ) available in MLE (Multi Language Environment).  After five
     seconds of the ending (including abnormal termination) of  a
     CS, cssd re-invokes the CS.

  CS STARTING INFORMATION FILE
     In a CS starting information file, /etc/css.conf by default,
     some  CS  starting  information  directories  are described.
     This file can be customized.  cssd  reads  /etc/css.conf  to
     get CS starting information directories, and then it invokes
     all executable files in the directories.  Usually,  each  CS
     itself  is  not  placed  in  the  directories and is invoked
     indirectly from a script in one of the directories.

  CS STARTING SCRIPT
     A CS starting script is located in a CS starting information
     directory.   cssd  reads  all CS starting information direc-
     tories in the sequence specified in /etc/css.conf and  finds
     to  invoke  all CS starting scripts.  If two or more scripts
     which have the same filename are found,  cssd  invokes  only
     the first one.

  UPDATING CS STARTING INFORMAION
     When cssd receives signal SIGHUP , it re-reads /etc/css.conf
     and  re-finds  all  CS  starting scripts, and then restarts,
     starts or terminates each script according to the  following
     conditions.

          A script whose modified time is changed (is to be  res-
          tarted)  A  script  which  is  newly  added  (is  to be
          started) A script which  is  deleted  (is  to  be  ter-
          minated)


  TO TERMINATE
     When cssd receives signal SIGTERM, it sends SIGTERM to  each
     CS  under  the  cssd's  management and terminates itself (in
     general, each CS also terminates with the signal).

  ERROR INFORMATION
     As a facility of daemon, cssd  sends  error  information  at
     level  `err'  ,  and  invoke/re-invoke  information at level
     `notice' to syslogd(1M).

OPTION
     -f filename
           Specify a CS starting information file.  Without  this
           option, /etc/css.conf is used.

FILE
     /etc/css.conf
           file for the information of CSs by default

SEE ALSO
     css.conf(4), cs00(1M), syslogd(1M)

BUGS
     If a CS starting script is  programmed  so  that  itself  is
     exec-ed by a CS, cssd understands that the process of the CS
     starting script is terminated in spite of the CS's  termina-
     tion, and so puts syslog message out.
