Indeed. I've tried to search again with the following script and got more such functions.
for func in `git ls-files | egrep "\w+\.h$" | xargs cat | egrep -v "(^typedef)|(DECLARE)|(BKI)" | egrep "^(extern )*[\_0-9A-Za-z]+ [\_\*0-9a-zA-Z]+ ?\(.+\);$" | sed -e "s/\(^extern \)*[\_0-9A-Za-z]\+ \([\_0-9A-Za-z\*]\+\) \{0,1\}(.*);$/\2(/g" | sed -e "s/\*//g"` do if [ "`git grep "$func" -- "*.c" | wc -l`" -lt 1 ];then echo $func fi done
Do we wish to make this a tool and have it in src/tools, either as part of find_static tool after renaming that one to more generic name or independent script.
