I know you meant that. My point was to describe what is the problem.
I wanted to understand what's going on as I don't know so much about the
code which is below the Lisp code and how it interacts with the C-code.

Do I understand correctly that when Emacs starts it tries to find the
file-handler in C but the call to the handler is done in Lisp code?

It is very interesting to learn how Emacs works on this level,
especially when going down into (X)Emacs past. Anyways that is another
topic.
