take this for instance
CvPointpoints[2];
id like to be able to cast points[2] to the CvPoint struct more info here http://docs.opencv.org/modules/core/doc/old_basic_structures.html?highlight=...
here is my struct which works for other things
;; (cffi:foreign-type-size '(:struct cv-point)) = 8 (cffi:defcstruct cv-point (x :int) (y :int))
put in a defparameter you cant just go
(defparameter points (cffi:foreign-alloc :int :count 2))
(defparameter a ((:struct cv-point) points))
you get an illegal function call error...any help is appreciated
