c-guess-buffer
c-guess-buffer is an interactive autoloaded compiled Lisp function in `cc-guess.el
'.
(c-guess-buffer &optional ACCUMULATE)
Guess the style on the whole current buffer, and install it.
The style is given a name based on the file's absolute file name.
If given a prefix argument (or if the optional argument ACCUMULATE is
non-nil) then the previous guess is extended, otherwise a new guess is
made from scratch.
