Hi Luis & James

I just started developing interface for monetdb DBMS mapi library and I'm using cffi for portability. So far I'm very pleased with cffi however I have 2 questions :

1. Is it possible to add documentation string to function defined with

defcfun macro

Right now it is discarded by DEFCFUN. It should be trivial to pass it on to the %DEFCFUN-* helpers instead. This should do it:

http://common-lisp.net/~loliveira/patches/defcfun-docstrings.diff

2. How to unload the library (dll, so) so cffi will unlock it and I could

change it , recompile it with c/c++ compiler.

CLOSE-FOREIGN-LIBRARY should work. However, I seem to recall that CLISP does funny things (and maybe SBCL/win32 too). My memory is very fuzzy about this, though. What are you trying to do (in what Lisp and OS) that doesn't work?
