Robert Yang 0424560e5f Add pidofproc to ${sysconfdir}/init.d/functions
Add pidofproc to ${sysconfdir}/init.d/functions, this is used for
getting the pid of the process. It uses pidof to implement currently, it
may also use the pidfile or ps to implement in the future.

--Shell-script--

functions This file contains functions to be used by most or all

shell scripts in the /etc/init.d directory.

NOTE: The pidofproc () doesn't support the process which is a script unless

the pidof supports "-x" option. If you want to use it for such a

process:

1) If there is no "pidof -x", replace the "pidof $1" with another

command like(for core-image-minimal):

ps | awk '/'"$1"'/ {print $1}'

Or

2) If there is "pidof -x", replace "pidof" with "pidof -x".

pidofproc - print the pid of a process

$1: the name of the process

pidofproc () {

# pidof output null when no program is running, so no "2>/dev/null".
pid=`pidof $1`
case $? in
0)
	echo $pid
	return 0
	;;
127)
	echo "ERROR: command pidof not found" >&2
	exit 127
	;;
*)
	return $?
	;;
