You mean Unix?

What about system headers?

Wrong. Examine argv[0], if it does have absolute path, stop. if it does
have relative path, start searching from current dir up to root, stop.
If it does not have path at all, start searching env var PATH, from
left to right, stop when executable is found. That's all.
