Now I want to define a C call back for that function:
(defcallback frgoc :void ((fmt :string) (args ???????
How do I define the callback such that I can have a C function with varargs being defined?
Sorry, no way to do that right now. Last time I checked, no Lisp's got support for such a feature. We might start using libffi to add extra (low-level) features in the near feature, but not even libffi supports this particular feature.
