I'm getting this this Error:

The value   (FOREIGN-ALLOC :POINTER :INITIAL-ELEMENT                  (POINT (UNIFORM RNG X-1 X-2)                         (UNIFORM RNG Y-1 Y-2))) is not of type   SB-SYS:SYSTEM-AREA-POINTER.    [Condition of type TYPE-ERROR]

My array is below, I simplified the array elements to (cffi:null-pointer)  I've been trying everything I can to create a 2d array of pointers. But its all  been coming down to this error: If anyone can help with this I'd be very appreciative.:)

(defvar *2d-array* #2A((

(foreign-alloc :pointer :initial-element (null-pointer))

(foreign-alloc :pointer :initial-element (null-pointer)))

((foreign-alloc :pointer :initial-element (null-pointer))

(foreign-alloc :pointer :initial-element (null-pointer)))))

(foreign-alloc :pointer                :initial-contents (make-array (reduce #'* (array-dimensions *2d-array*))                                              :displaced-to *2d-array*))
