Can't turn on auto-fill-mode in c-mode (is it only for text-mode??)

Can't turn on auto-fill-mode in c-mode (is it only for text-mode??)

[Christian Seberino]

"emacs aa" opens a new file and I can do M-x auto-fill-mode to put it
into auto-fill-mode.  (I nuked .emacs so that won't be a red herring.)

"emacs aa.c" throws it into c-mode (cc-mode?) and M-x auto-fill-mode
has no noticeable effect.  

HOW COME AUTO-FILL-MODE DOESN'T WORK IN C-MODE???

Chris,

I see that in Emacs-21 the default value of auto-fill-function for 
c-mode is c-do-auto-fill, which is defined in 
lisp/progmodes/cc-cmds.el.  (Emacs-20 uses plain old do-auto-fill.)

While visiting your .c file, try changing auto-fill-function (which 
is a buffer-local variable) to 'do-auto-fill, and see if it behaves 
more like you would expect.  If so, then you might want to 
investigate what the difference is between c-do-auto-fill and plain 
old do-auto-fill.

I'm impressed and amazed that you found this info out.
I grep'ed thru the Emacs Lisp Ref Manual for ver. 21
and there was not one place where they mentioned
c-do-auto-fill.  How did you find this out?!?!

I cannot believe it is this difficult to set this mode
for c-mode.  Surely I cannot be the only one that
uses Emacs for programming and wants to keep his code
from being as wide as 2 pages!??!?

Please tell me if you don't mind
the proper to turn on c-do-auto-fill so that
it only activates in c-mode and doesn't mess up other
modes.

thanks,

Chris

P.S. BTW is there a difference between c-mode and cc-mode??
I turn on c-mode but I see messages about cc-mode appear
when Emacs turns on.  I dunno.
