Finding the parent function in emacs

Have you ever been in the middle of a really long function and wondered just exactly what it was called? Angus Lees came up with

(defun print-defun-name ()
  (interactive)
  (save-excursion
    (beginning-of-defun)
    (beginning-of-line 0)
    (let ((start (point))
          string)
      (end-of-line 2)
      (setq string (buffer-substring start (point)))
      (message "%s" (replace-regexp-in-string "[ \t\n]" " " string)))))

I came up with a slightly different version that works a little better for C code

(defun c-print-defun-name ()
  (interactive)
  (save-excursion
    (c-beginning-of-defun)
    (end-of-line 0)
    (let ((end (point)))
      (c-beginning-of-statement)
      (let ((start (point)))
        (setq string (buffer-substring start end))
        (message "%s" (replace-regexp-in-string "[ \t\n]+" " " string))))))

Add it to your .emacs and if you really want, bind it to a key.
