[cffi-devel] Re: unnamed callback (closures?)

In CLISP, every closure can be turned into a callback, and this is valuable since it allows to retrieve context information out of the closure. Is cffi's limitation caused by some implementations?

To my knowledge, yes. AFAICT, only SBCL/x86 and CLISP support that. Regarding the behaviour of CFFI:DEFCALLBACK as a non-toplevel form, not only will it set it globally, the callback itself won't be generated at runtime on most Lisp, IIRC. -- Luís Oliveira luismbo (@) gmail (.) com Equipa Portuguesa do Translation Project http://www.iro.umontreal.ca/translation/registry.cgi?team=pt
