A void pointer is a pointer to an unknown type and you should cast to a
specific type before using it. For this reason this line is invalid and
vala should complain at compile time like the C compiler is doing:
ulong xid = (ulong) list[i];
You are accessing the list variable with "list[i]".
I think that you can workaround this situation with a temporary variable
and honestly I don't know a cleaner solution:
unowned ulong[] items = (ulong[])list;
for (int i = 0; i < nitems; i++) {
ulong xid = items[i];
stdout.printf(xid.to_string());
}
