How to give a list as arguments to a function in elisp?

Question

I'm trying to learn elisp and emacs customization. I setq'ed a list of arguments to a variable. How do I go about passing this list to a function instead of just giving the arguments directly.

Thanks in advance.

Answer 1

Use the apply function:

(apply 'function arglist)

For example:

(apply '+ '(1 2 3 4))
==> 10
