Is there any uniform way of passing C null value to functions? Should I pass `0'?

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.
