How do I create a scheme list inside a C function, and return that
list? I couldn't find any documentation on this, so I searched through
gambit.h and came up with this, which fails to compile due to "___hp"
being "undeclared".
___hp seems to be used in the definition of ___CONS.
;;========================================
;; Is this the correct way to create lists?
(c-declare #<<c-declare-end
___SCMOBJ getList () {
___SCMOBJ *a, *b, *c;
___S8 one, two, three;
one = 1;
two = 2;
three = 3;
return
___CONS(one,
___CONS(two,
___CONS(three,
___NUL)));
}
c-declare-end
)
(define get-list
(c-lambda () scheme-object "getList"))
(read) ;So that I can enter the REPL by interrupting the program.
