Hi list! Background: I'm trying to write a CFFI interface to the silc client library (see silcnet.org), for use with my silcbot. This is on SBCL 0.9.11, Debian sarge, CFFI-tarball from 2006-04-24, silc toolkit 1.0.2. Problem: the silc client library needs callbacks with variable argument lists. Is there a portable way to access these arguments? Possible solutions: - I could define additional arguments to fit the maximal size of the argument list, and do some byte-shifting if necessary. Yuck! - This should be possible to do in ECL. Cons: I lose portability, and ECL does not seem to be as widely supported on Linux as SBCL (libraries might break), and since this is my first CL-project I don't feel like patching libraries myself yet. Has anyone a better idea how to accomplish this? Regards, Anselm
