Check if inside a function definition

Check if inside a function definition

[Nordlöw]

Is there a function that check whether I am standing inside a function
in C/C++?

Is c-in-function-trailer-p the best Emacs can currently do?

Look up the "Which Function" menu option in Senator/modes having loaded
Senator via the CEDET package. Lots of nice formatting goodies there
but can be a tad confusing at times (senator, semantic etc - it still
confuses me:-;).

See here for details:

Yes.

No.  :-)

The function you want is `c-where-wrt-brace-construct', the very next
function after `c-in-function-trailer-p' in cc-cmds.el.  It returns a
symbol as detailed in the function's header comment:

;; Return one of these symbols:
;; at-header       : we're at the start of a function's header.
;; in-header       : we're inside a function's header, this extending right
;;                   up to the brace.  This bit includes any k&r declarations.
;; in-block        : we're inside a function's brace block.
;; in-trailer      : we're in the area between the "}" and ";" of something
;;                  like "struct foo {...} bar, baz;".
;; at-function-end : we're just after the closing brace (or semicolon) that
;;                   terminates the function.
;; outwith-function: we're not at or in any function.  Being inside a
;;                   non-brace construct also counts as 'outwith-function'.

'at-header, 'at-function-end and 'outwith-function, I think, all count as
not being being inside a function, though depending on what you want,
you might prefer either or both of these boundary symbols to cound as
"in".

This function is not currently regarded as being in the "public
interface" part of CC Mode, but I think I'm likely to make it such a
function soon.
