     42  * that it's broken when getting metadata for a SINGLE object.

     44  * may not return a proper count of the objects, and sometimes
     45  * (like on the ZENs) objects are simply missing from the list
     46  * if you use this. Sometimes it has been used incorrectly to

     48  * with size given to -1 (0xFFFFFFFFU), in that case please
     49  * help us remove it now the code is fixed. Sometimes this is
     50  * used because getting all the objects is just too slow and
