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()); } Regards, Andrea _______________________________________________ vala-list mailing list vala-list@gnome.org http://mail.gnome.org/mailman/listinfo/vala-list
