It sounds like you want foreign-slot-value. http://common-lisp.net/project/cffi/manual/html_node/foreign_002dslot_002dvalue.html#foreign_002dslot_002dvalue You could wrap this in a helper function or macro to make it shorter for the common cases. It would take a great deal more work to get a short o...

The parameters are evaluated when you type them in, before they are passed to the lambda form. Use a quote to protect the character. (Or a macro if quotes aren't allowed.)

What data structure are you using to store the game board? (Or what type of structure do you want to use?)

Ahh, this forum is not very busy with AutoCAD users. We have a list of links to other sites that may be more helpful.

Subject: "how do i pass structs by value with cffi-libffi?"
Body: similar to your post here, possibly a link here.

Could you provide more details on what you want to do and any possibilities you have considered?

Is this a homework problem?

Is this something like what you want?

Code: Select all

(let ((x (make-array '(3 4) :initial-element 2)))
  (dotimes (m (array-dimension x 0))
    (dotimes (n (array-dimension x 1))
      (format t "~A " (aref x m n)))
    (format t "~%")))

I really think the Lisp community needs to engage the C/C++ community more. Look at the success Clojure (JVM Lisp) has had to get a feel for the possibilities. Its not always glorious work, but it grants rapid access to large repositories of existing code. ECL is a good implementation for such tasks...

When you reach a nested list, you need to traverse down that branch and also keep traversing the current list...
