emacs functions for editing C

[Bill Poser]

There are a number of functions I would like to have available
in (GNU)EMACS for editing C code that are not to my knowledge
part of the C major mode. The functions that come to mind are:

	goto-beginning-of-function
	goto-end-of-function
	name-current-function

Before I set out to write them, I'd like to enquire as to whether
anyone has done this.

(I'd also love an extension to etags that created tags for
external identifiers.)
