[cffi-devel] Can closures be used as callbacks in CFFI?

18 Sep 2007

      Dear developers,

can closures be used as callbacks, i.e. will the following kind of code work?

(let ((ptr nil))
  (let ((a 3))    
    (defcallback add-a :int ((b :int))
      (+ a b))
    (setq ptr (callback add-a)))
  (c-function ptr))

Best regards
