You should probably use the pointer type:
(with-foreign-object (capture** :pointer)
(setf (cffi:mem-ref capture** :pointer) capture*)
(%release-capture capture**))
Enhancing with-foreign-object such that it accepts the same arguments
as foreign-alloc is in my wish list. That would help make this example
more concise.
