I need a function that will kill a (named) buffer if it exists.
1)Is there one?
  a)If not, I will need a function that checks for the existance
    of a buffer by name.
  b)Is there one?
Pointers to docs, resources welcomed.

I don't recall where I came by this, on this group probably...


(defun kill-buffers-matching (regexp)
  (interactive "sKill buffers matching: ")
  (dolist (i
	   (buffer-list))
    (when (string-match regexp (buffer-name i))
      (kill-buffer i))))

(get-buffer NAME)

Use C-h get-buffer RET to get basic documentation.

In the Elisp manual you can look under "Buffers" - "Buffer Names". 

If you are using CVS Emacs (next generation of Emacs, not yet released) 
you can find this manual by first selecting from the menus "Help - Read 
Emacs Manual" and then then choose Emacs Lisp. If you are using current 
Emacs (version 21.3) it can happen that it is not installed by default.

How about (kill-buffer (get-buffer "blabla")) ?

C-h f get-buffer

Yes

Thank you folks!

You have me on the right track (I think).

I believe something like:
(if (get-buffer "*Help*")(kill-buffer "*Help*"))
will do the trick.

Cheers

Well, actually just:
  (kill-buffer (get-buffer "blabla"))
works for me (but I use EmacsCVS, it may behave differently in 21.4 or
whatever you are using).

Anyway, for me get-buffer returns nil if no matching buffer is found,
and (kill-buffer nil) seems to be a no-op.

Err.

(kill-buffer nil) kills the current buffer, which is no no-op.

Hmm... funny... 

<goes back to his test case> ... <comes back with a brown paper bag
over his head> Yes, you are right... my testing was flawed: I have
forgotten my *scratch* buffer is protected against killing.

Sorry about that.
