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.

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
