c-initialize-cc-mode is an autoloaded compiled Lisp function in `cc-mode.el'.

(c-initialize-cc-mode &optional NEW-STYLE-INIT)

Initialize CC Mode for use in the current buffer.
If the optional NEW-STYLE-INIT is nil or left out then all necessary
initialization to run CC Mode for the C language is done. Otherwise
only some basic setup is done, and a call to `c-init-language-vars' or
`c-init-language-vars-for' is necessary too (which gives more
control). See "cc-mode.el" for more info.
