[cffi-devel] CFFI and SBCL

[Immanuel Litzroth]

Dear List,

I tried out CFFI on SBCL linux yesterday and would like to give some feedback. 
1) On SBCL the rt package is named sb-rt.
2) The string callback test does not compile nor does the qsort callback test.
3) All the other tests run.

I also have the following observations. 
* SBCL and CMUCL have alien integer types that can specify a number of bits. 
I have had success in optimizing lisp ffi by restricting values to xx bits 
so they can be immediately translated to fixnums. It seems a shame to lose this
possiblity in a cffi.

* I often need to allocate foreign objects and put them in a lisp struct. I would
then want to run a finalizer if the struct gets garbage collected, to free the allocated
memory. A nice interface to the finalizer functionality on different systems would 
be a great feature for cffi.
