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

Possible solutions:
- Write a C callback -- or wrapper around the relevant functions, depending upon the callback registration style -- that array-ifies the valist.
