8192 is NOT a magic number.  It specifies the # of 32 bit quantities to be retrieved.  This will vary completely from application to application.
If you are using 8192 indiscriminately, then you will probably be having mucho core dumps.

For instance, to retrieve 56 longs from a property, you
would use 56 as the 5th argument.

To retrieve 68 shorts from a property, you would use 34 as the 5th argument.
