The former:

(use dollar)

(define h1 ($ c-pointer HBox (c-pointer child1) (c-pointer child2)
(c-pointer child3)))

But if you want more type-safety, or a general Scheme-interface (not just
use HBox in some code), then you should indeed consider creating a
pointer list in C, or converting a Scheme list to such a pointer list).
