suppose I have c code of:
[1] foo *bar = get_foo(); [2] if (bar != NULL) { ... }
in scheme, I have
(let ((bar (get-foo))) [1] [2] <-- how do I write this line in scheme?
(if bar (do-something-with bar) (do-something-else))
(get-foo) should evaluate to #f if there is no bar.
You should give #scheme a try for such basic questions.
Good luck,
