[Ecls-list] retrieving values returned by lisp function in C programs

i somehow managed to retrieve my lisp functions from my C program:
int main(int argc, char** argv) {
extern void init_TEST(cl_object);
cl_boot(argc,argv);
read_VV(NULL,init_TEST);
}
the way i use to call the lisp functions is:
cl_object form = c_string_to_object("(my_function arg)");
eval(form, NULL, Cnil);
this works pretty well, unless i need the values returned by my_function.
the eval() function return a cl_object of type t_symbol. i tried to look up the global array Values, with my_function being:
(defun my_function () (values 8 9))
but only Values[0] is a valid cl_object, of type t_symbol.
i'm sure i'm not doing that the right way, but i really can't find anywhere what the right way is.
i'll be glad to be some help on that :)
thanks
