The function to show current file's full path in mini buffer

Question

I need to get the full path of the file that I\'m editing with emacs.

• Is there a function for that?
• If not, what would be the elisp function for getti

Answer 1

The simplest way and would be

(buffer-name)<(C-x)(C-e)> for the file name to appear in the echo area

(buffer-name)<(C-u)(C-x)(C-e)> would print the location 

Borrowing from Trey Jackson I came up with this:

(defun buffer-kill-path ()
  "copy buffer's full path to kill ring"
  (interactive)
  (kill-new (buffer-file-name)))
