checking for empty arrays

[Mike Gorse]

Hi all,

Is there a good way to check for an empty array using libdbus?  I want to 
avoid calling dbus_message_iter_recurse on the array iter if the array is 
empty, since I think that causes a crash.  Currently I have code like 
this:

   dbus_message_iter_recurse (&iter, &iter_array);
   if (dbus_message_iter_get_array_len (&iter_array) > 0) do
     {
       ...
     }
   while (dbus_message_iter_next (&iter_array));

But the above is not good because dbus_message_iter_get_array_len is 
deprecated.  I cannot use dbus_message_iter_get_fixed_array because I have 
an array of structures, and I haven't found a way to check that there is 
data at the original position before recursing into it.

Thanks,
-Mike
