### BEGIN INIT INFO
# Provides:          lirc
# Required-Start:    $remote_fs
# Required-Stop:     $remote_fs
# Default-Start:     3 5
# Default-Stop:      0 1 2 6
# Short-Description: lirc daemon
# Description:       The  main  task  of lircd is to decode the infrared
#	signals and provide an uniform interface for client applications
### END INIT INFO

# Check for missing binaries (stale symlinks should not happen)

# Check for existence of needed config file and read it

# providing start_daemon, killproc, pidofproc, 
# log_success_msg, log_failure_msg and log_warning_msg.
# This is currently not used by UnitedLinux based distributions and
# not needed for init scripts for UnitedLinux only. If it is used,
# the functions from rc.status should not be sourced or used.

# Shell functions sourced from /etc/rc.status:
#      rc_check         check and set local and overall rc status
#      rc_status        check and set local and overall rc status
#      rc_status -v     ditto but be verbose in local rc status
#      rc_status -v -r  ditto and clear the local rc status
#      rc_status -s     display "skipped" and exit with status 3
#      rc_status -u     display "unused" and exit with status 3
#      rc_failed        set local and overall rc status to failed
#      rc_failed <num>  set local and overall rc status to <num>
#      rc_reset         clear local rc status (overall remains)
#      rc_exit          exit appropriate to overall rc status
#      rc_active	checks whether a service is activated by symlinks
#      rc_splash arg    sets the boot splash screen to arg (if active)
. /etc/rc.status

# Reset status of this service

# Return values acc. to LSB for all commands but status:
# 0	  - success
# 1       - generic or unspecified error
# 2       - invalid or excess argument(s)
# 3       - unimplemented feature (e.g. "reload")
# 4       - user had insufficient privileges
# 5       - program is not installed
# 6       - program is not configured
# 7       - program is not running
# 8--199  - reserved (8--99 LSB, 100--149 distrib, 150--199 appl)
# 
# Note that starting an already running service, stopping
# or restarting a not-running service as well as the restart
# with force-reload (in case signaling is not supported) are
# considered a success.
