Re: Declared but no defined functions

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
