(info "(elisp) Killing Buffers")

I was already reading that page but it doesn't seems to suggest a
solution.

What about the hooks there?

Namely, how to make kill-buffer ask user to save, for buffers that's
not associated with file.

looking at Aquamacs's source... looks like the “solved” it by actually
define its own kill-buffer wrapper, e.g. close-current-window-
asktosave.

when i create a new buffer, how can i make emacs ask to save if it is
modified?
for example, i have this function:
(defun new-empty-buffer ()
  "Opens a new empty buffer."
  (interactive)
  (let ((buf (generate-new-buffer "untitled")))
    (switch-to-buffer buf)
    (funcall (and initial-major-mode))
    (setq buffer-offer-save t)
))
after calling, it'll create a new buffer. Then, if user edit the
buffer, then close it (using either kill-buffer or kill-this-buffer),
then i want emacs to ask whether to save it if the buffer has been
modified.
according to the manual, the var buffer-offer-save will do it only if
the buffer is a visiting buffer. Then the manual talks about save-some-
buffers second argument but i don't see how this fits together, since
i don't actually want to call save-some-buffers.
