c-electric-paren
c-electric-paren is an interactive compiled Lisp function in `cc-cmds.el
'.
(c-electric-paren ARG)
Insert a parenthesis.
If `c-syntactic-indentation' and `c-electric-flag' are both non-nil, the
line is reindented unless a numeric ARG is supplied, or the parenthesis
is inserted inside a literal.
Whitespace between a function name and the parenthesis may get added or
removed; see the variable `c-cleanup-list'.
Also, if `c-electric-flag' and `c-auto-newline' are both non-nil, some
newline cleanups are done if appropriate; see the variable `c-cleanup-list'.
