The thing is, at first I thought, am I going to repeat the same exact
words as in the DESCRIPTION?

DESCRIPTION
     strnul() returns a pointer to the terminating null byte in the
     string s.

RETURN VALUE
     strnul() returns a pointer to the terminating null byte in the
     string s.

I could remove the DESCRIPTION altogether...  What would you do?

I might as well write it as &s[strlen(s)] if pointer arithmetic is the
confusing part.  :)

I intend old programmers to use it too.  I guess you're expecting
a patch to groff once this is in a branch of gnulib you're using.  ;)

Agree.


Have a lovely night!
