C Mode Comments

[Kevin Dziulko]

Does anyone know if there is a command to mark a comment, or kill a
comment in c-mode?

Thanks much.

Did you mean "comment-region" and "uncomment-region" commands?

I am running GNU Emacs 20.2.3.  M-; does not run comment-dwim, but runs 
indent-for-comment.

What I am looking for is a command that would have the effect of killing 
an entire comment.  For example, given:

int x;      /* this is a comment */

Only "int x;" would remain on this line of code.

Thanks.

It might work to say C-u M-;.

You could try to search for a file newcomment.el, it might have been
posted to gnu.emacs.sources and this version might work with your
Emacs.  Or it might not.  Maybe it's easier to just upgrade your
Emacs.  This is very easy to do, if you have enough space in your
home dir, say.
