Preventing indentation of statements inside #ifdef __cplusplus....

Preventing indentation of statements inside #ifdef __cplusplus....

[Nordlöw]

How can I instruct Emacs *not* to indent declarations and definitions
such as the statement foo(); between the following standard snippets?:

#ifdef __cplusplus
extern "C" {
#endif

foo();

#ifdef __cplusplus
}
#endif


Thanks,
Nordlöw

You can define and use the following style.

1. Add to your .emacs:
  ;;; C++ style: don't indent namespaces
  (c-add-style "my_style"
             '("user"
               (c-offsets-alist
                (inextern-lang . 0))))
2. In the buffer, try "C-c . my_style RET" to try it out, then if
satisfied "M-x customize-variable c-default-style RET" and set up c++-mode
to use my_style.

Note that the above *always* inhibits indentation of extern "C" bodies, not
just those #ifdef'ed out.  I consider this the right thing to do -- you
might not.

Hope this helps,
