In particular, how to know whether a pointer is actually NULL? I noticed that it's not converted to CL's nil, but a wrapper that contains the NULL pointer inside.

Of course I can hack it by checking whether (format nil "~A" the-pointer) contains the substring null, but I think there should be a better solution.
