In /etc/init.d/functions:

pidofproc() {
        local RC pid pid_file=

        # Test syntax.
        if [ "$#" = 0 ]; then
                echo $"Usage: pidofproc [-p pidfile] {program}"
                return 1
        fi
        if [ "$1" = "-p" ]; then
                pid_file=$2
                shift 2
        fi
        fail_code=3 # "Program is not running"

        # First try "/var/run/*.pid" files
        __pids_var_run "$1" "$pid_file"
        RC=$?
        if [ -n "$pid" ]; then
                echo $pid
                return 0
        fi

        [ -n "$pid_file" ] && return $RC
        __pids_pidof "$1" || return $RC
}

other routines:

# __proc_pids {program} [pidfile]
# Set $pid to pids from /var/run* for {program}.  $pid should be declared
# local in the caller.
# Returns LSB exit code for the 'status' action.
__pids_var_run() {
        local base=${1##*/}
        local pid_file=${2:-/var/run/$base.pid}

        pid=
        if [ -f "$pid_file" ] ; then
                local line p
                read line < "$pid_file"
                for p in $line ; do
                        [ -z "${p//[0-9]/}" -a -d "/proc/$p" ] && pid="$pid $p"
                done
                if [ -n "$pid" ]; then
                        return 0
                fi
                return 1 # "Program is dead and /var/run pid file exists"
        fi
        return 3 # "Program is not running"
}

# Output PIDs of matching processes, found using pidof
__pids_pidof() {
        pidof -c -o $$ -o $PPID -o %PPID -x "$1" || \
                pidof -c -o $$ -o $PPID -o %PPID -x "${1##*/}"
}
