Function: c-lineup-gnu-DEFUN-intro-cont

c-lineup-gnu-DEFUN-intro-cont is a byte-compiled function defined in cc-align.el.gz.

Signature

(c-lineup-gnu-DEFUN-intro-cont LANGELEM)

Documentation

Line up the continuation lines of a DEFUN macro in the Emacs C source.

These lines are indented c-basic-offset columns, usually from column 0. Return nil when we're not in such a construct.

This function was formally for use in DEFUNs, which used to have knr argument lists. Now (2019-05) it just indents the argument list of the DEFUN's function, which would otherwise go to column 0.

Here is an example:

DEFUN ("forward-char", Fforward_char, Sforward_char, 0, 1, "p",
       doc: /* Move point right N characters (left if N is negative).
On reaching end of buffer, stop and signal error. */)
  (Lisp_Object n) <- c-lineup-gnu-DEFUN-into-cont

Works with: topmost-intro-cont.
