Just use grep to check like below, then filter out known false item

grep -rP --include=*.h '^(?:\w+\s+){1,3}\*{0,3}\s{0,3}\w+[\t]*\(' * |grep -P -oh '\w+\s*\('|sort| uniq -c| sort -n| grep -P '^\s+1\b'|sed -r -e 's/^\s+1\s+//' -e 's/\(//'|while read line ;
 do
        CNT=`git grep -w $line |wc -l` ;
        if [ $CNT -eq 1 ];then
                git grep -wn $line
        fi
done
