I'm not able to insert values into a Ruby array, and retrieve them later.
I put the results of different lines that I tried inside the first function. The results are:
VALUE rStraightCards;
static VALUE check_for_straight() {
stuff...
if (begin_straight != NOT_FOUND) {
for (i = begin_straight; i >= end_straight; i--) {
// this gives me a segmentation fault when I call straight_cards()
rb_ary_push(rStraightCards, i);
// these lines give me an empty ary when I call straight_cards()
// RARRAY_P开发者_StackOverflow社区TR(rStraightCards)[i] = i;
// RARRAY_PTR(rStraightCards)[INT2NUM(i)] = INT2NUM(i);
}
}
}
VALUE straight_cards() {
return rStraightCards;
}
void Init_straight_count() {
rStraightCards = rb_ary_new2(NUM_CARDS);
}
Both arguments for rb_ary_push
are supposed to be of type VALUE
but you're pushing an int
(probably):
VALUE
rb_ary_push(VALUE ary, VALUE item)
{
rb_ary_modify(ary);
return rb_ary_push_1(ary, item);
}
Try this:
rb_ary_push(rStraightCards, INT2NUM(i));
I think it is worth noting that VALUE
will usually be defined like this:
typedef uintptr_t VALUE;
So the usual warning flags for int-to-pointer conversions won't catch this sort of error.
