Does anyone know of a C library for handling Emacs-like backup files?
E.g., if writing a file, the function would do the right thing.

And all the other nice things that come with Emacs.

I know that GNU Indent uses a similar backup system, and looking at
their backup code[0] it seems fairly self-contained.  Perhaps it could
be extracted into a separate library?

There is backupfile in gnulib.

Coreutils do that, no?  E.g., "cp -b".

_All_ of them?  That's Emacs, I guess.

dired-async.el provides a backup function similar to
cp -f --backup=numbered from to.

Probably you can say instead: Thank you for your answer but it is not
what I am looking for.

Have a good evening.

Isn't everything C, if you squint a bit? (Now i'll have all the SBCL,
Haskell and Rust folks all over me -- but definitely, Emacs lisp
is C at a lower layer ;-)

But seriously: you could have been nicer in response to a honest
mistake.

Cheers
