Hi All,
I'm starting to look into libguile/foreign.c to add support for libffi's
variadic
function calls. My thinking is that that pointer->procedure would accept '...
as
the last element of the arg list, and that on procedure calls one would pass a
pair
to for each unspecified argument. The car of the pair is the ffi type (e.g.,
int)
and the car is the value.
(use (system foreign))
(define scm-printf (pointer->procedure int (dynamic-func "printf") ('* '...)))
(scm-printf (string->pointer "ans=%d\n") (cons int 4))
Comments?
Matt
