Glad you were able to fix this issue! You should pass (cffi:null- 
pointer). CLISP does convert NIL to the null pointer which is  
unfortunate for this reason (Hi
Joerg!) :-) And it seems Lispworks does too.

The lack of uniformity is very unfortunate here. This needs to be  
fixed. We should either a) translate nil->null everywhere, b) don't  
translate nil->null anywhere or c) offer the two alternatives through  
two different types.
