In Elisp:
I want to create an alias for Emacs' c-guess-basic-syntax function,
something like this:
(defalias 'c-old-guess-basic-syntax 'c-guess-basic-syntax)
(defun c-guess-basic-syntax ()
(some logic here)
(c-old-guess-basic-syntax))
So, I want to create a hook for c-guess-basic-syntax that runs before
the original function and then calls the original function. I don't want
to modify the original function code to add this hook.
The above doesn't work because c-old-guess-basic-syntax doesn't
actually hold a reference to the original c-guess-basic-syntax but to
my newly created one.
How to achieve the above in elisp ?

Use an advice:
(defadvice c-guess-basic-syntax (before karols-cool-advice)
"I run before `c-guess-basic-syntax' runs."
(message "Hey, I'm a piece of advice."))
Bye,
