c-lang-constc-lang-const is a Lisp macro in `
cc-defs.el'. (c-lang-const NAME &optional LANG) Get the mode specific value of the language constant NAME in language LANG. LANG is the name of the language, i.e. the mode name without the "-mode" suffix. If used inside `c-lang-defconst' or `c-lang-defvar', LANG may be left out to refer to the current language. NAME and LANG are not evaluated so they should not be quoted.
