You can change it temporarily by putting the cursor on the second line
and pressing "C-c C-o". Minibuffer dialog offers arglist-cont-nonempty:
just press Enter and then answer ++ (that is, two plus signs) to the
latter question.

You can also add your own styles. This example adds a style called
"my-style" which is based on "linux" style. We put the style definition
to c-mode-common-hook so that it gets defined when turning on a
programming mode that is managed by Emacs cc-mode package.

    (add-hook 'c-mode-common-hook
              '(lambda ()
                 (c-add-style
                  "my-style"
                  '("linux" (c-offsets-alist
                             (arglist-cont-nonempty '++))))))

Then change to that style with "C-c ." or c-set-style function.



Another possibility to get the new style added is "(eval-after-load
'cc-mode '(c-add-style ...))".

Good tip, thanks.

Yup, I found out that `arglist-cont-nonempty' was the key.

c-mode indentation of parenthesized expressions

[Thomas Christensen]

Hi,

Emacs per default indents like this in all c-styles I have tried:

a = (2 + 4 +
     5)

and

a = foo(1, 2, 3,
        4)

It aligns with the parenthesis.

I want to change this to twice the default indent, which I have set to a
tab in the example below, like this:

a = (2 + 4 +
		5)

and

a = foo(1, 2, 3,
		4)

Can someone tell me how to do this?

I have messed around with `c-style-alist'; but without any luck.

Sorry for the noise, I just found out.
