Hook questions

Hook questions

[Hadron Quark]

1) Whats the difference between, say c-mode-hook and c-mode-common-hook?

2) If I "describe-mode" for while editing a c file I see the hook name
   documented as :

,----
| The hook `c-mode-common-hook' is run with no args at mode
| initialization, then `c-mode-hook'.
`----

The info mode (while reading info files) reveals no such hook. Can I
create one out of the blue?

Thanks for your patience -  theres a lot to learn and sometimes the
amount of info online and in emacs makes it hard to locate the info to
questions that pop up mid "discovery" as it were.

Try the "CC Mode" manual (info "(ccmode)CC Hooks"):

    -- Variable: c-mode-common-hook
        Common hook across all languages.  It's run immediately before
        the language specific hook.

    -- Variable: c-mode-hook
    -- Variable: c++-mode-hook
    -- Variable: objc-mode-hook
    -- Variable: java-mode-hook
    -- Variable: idl-mode-hook
    -- Variable: pike-mode-hook
    -- Variable: awk-mode-hook
        The language specific mode hooks.  The appropriate one is run
        as the last thing when you enter that language mode.

Thanks. I feel like such a prick sometimes when I miss this stuff. But
there is so much info in so many different places I sometimes give up
and reach out for help. Thanks a lot.

Anyway, I mean, "c-mode-common-hook" : who would have guessed its for
ALL languages. It begins with "c" :(
