Since the return type of Pack is an array (a reference),
you must not unpack it. You can start accessing it:

DataLink *elem0 = mono_array_get (retLinks, DataLink*, 0);
DataLink *elem1 = mono_array_get (retLinks, DataLink*, 1);

It depends what the IntPtr actually is. If it's the result
of Marshal.StringToHGlobalUni() then it's most likely OK.
