### 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)
lircd_BIN=/usr/sbin/lircd
test -x $lircd_BIN || exit 5
# Check for existence of needed config file and read it
lircd_CONFIG=/etc/sysconfig/lirc

# Source LSB init functions
# 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.
#. /lib/lsb/init-functions
# 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
rc_reset
# 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.
