Well, my system reports c++-mode for *.h files as well. Original
poster specifically asked the function to apply to *.c files only.

docstring for looking-at suggests it looks at text after point, while
the needed one seems to be before the point. Sure you can move to the
beginning of line first, but then I fail to see the benefit...

(if (string-match ".*return;"
        (buffer-substring (line-beginning-position) (point)))
     ...
 ...)

Well, OK, your version is shorter :)

Ah, yes, I always forget this one... Thanks :)
