How to detach buffer?

[Matthias Pfeifer]

Hello,

is it possible to detach a buffer from a multi-window frame? Talking elisp

(defun detach-buffer ()
 (interactive)
 (let ((buf (current-buffer)))
   (delete-window)
   (select-frame (make-frame))
   (set-window-buffer (selected-window) buf)
   )
 )

So even the question seems answered i actually like to know if i
reinvent the wheel. ie is a function like my detach-buffer already
available?
