When my c++ mode hook is run, I want to print the value of some variables

When my c++ mode hook is run, I want to print the value of some variables

[Eric Lilja]

How do I do that?

(defun my-cpp-mode-hook ()
  (message "Running my-cpp-mode-hook")
  (c-set-style "ellemtel")
  ; Say I want to print the value of access-label here, how? I can set
it with (c-set-offset 'access-label '-)
)
(add-hook 'c++-mode-hook 'my-cpp-mode-hook)

Is access-label even a variable? How do I print its value?

I'm running GNU Emacs 22.0.93.1 (i386-mingw-nt5.1.2600) of 2007-02-20
on MINDCOOLER

I know about the command C-c C-o btw...

Short answer:
(print (assoc 'access-label c-offsets-alist))

Then go look in *Messages* for the value

Less-short answer:
If you look at the docs for c-set-offset (C-h f, c-set-offset), you'll
see that it changes the value associated with the symbol access-label
in the associative list c-offsets-alist.  That list is the actual
variable that you are modifying.
