c - 如何在C中获取文件中所有函数的范围(即行号)？

Question

我想在C中获取一个文件中所有函数的开始和结束行号，有没有人知道Linux中是否有用于此目的的易于使用的工具？

Answer 1

$ ctags -x --c-kinds=f filename.c

This only gives the starting line of each function, but perhaps that is good enough.

If the code was written using fairly common conventions, the function should end with a single line containing } in the first column, so it is fairly easy to get the last line given the first:

awk 'NR > first && /^}$/ { print NR; exit }' first=$FIRST_LINE filename.c
