(FOREIGN-ALLOC... is is not of type SB-SYS:SYSTEM-AREA-P...

I was hoping someone could look at this and help me debug it.

I'm getting:

  (FOREIGN-ALLOC :POINTER :INITIAL-ELEMENT (NULL-POINTER))
is not of type
  SB-SYS:SYSTEM-AREA-POINTER. when I run it.

(foreign-array-alloc #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-element (null-pointer)) 
			  (foreign-alloc :pointer :initial-element (null-pointer))) 
			 ((foreign-alloc :pointer :initial-element (null-pointer)) 
			  (foreign-alloc :pointer :initial-element (null-pointer)))) '(:array :pointer 4 2))

 

there is no function foreign-array-alloc or foreign-alloc in common lisp (by default). please say, where you got this function

(I think the second code is the one you wrote to get this message)

Or never mind...I just found out how to create a 2d pointer array...that was CFFI btw

(cffi::foreign-array-alloc
 (make-array '(4 2) :initial-contents
             (list (list (cffi:foreign-alloc :pointer :initial-element (c-pointer (point 1 2))) 
                         (cffi:foreign-alloc :pointer :initial-element (c-pointer (point 1 2))))
                   (list (cffi:foreign-alloc :pointer :initial-element (c-pointer (point 1 2))) 
                         (cffi:foreign-alloc :pointer :initial-element (c-pointer (point 1 2)))) 
                   (list (cffi:foreign-alloc :pointer :initial-element (c-pointer (point 1 2))) 
                         (cffi:foreign-alloc :pointer :initial-element (c-pointer (point 1 2)))) 
                   (list (cffi:foreign-alloc :pointer :initial-element (c-pointer (point 1 2))) 
                         (cffi:foreign-alloc :pointer :initial-element (c-pointer (point 1 2))))))
 '(:array :pointer 4 2))
