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 ...))".
