C-. keybinding in (X)Emacs

[Yan Tang]

Hi, I want to bind `C-.' to some func in (X)Emacs, but I don't know how to 
define the key.
(global-set-key "\C-." *****) doestn't work.

And in XEmacs, (global-set-key '(control period) *****) doesn't work either.

(global-set-key "\M-." *****) works well, but I have reserved it for etags.

So how to define C-. keybinding?

Thanks in advance!
