I will recommend YAsnippet package to you [ code.google.com/p/
yasnippet ]
and
(add-hook 'c-mode-hook
          '(lambda ()
              (setq yas/buffer-local-condition
                    '(if (nth 8 (syntax-ppss (point)))
                         '(require-snippet-condition . force-in-
comment)
                       t))))
will do what you want.
