+Routine Description:

+

+  This is the function that is called to provide results data to the driver.  This data

+  consists of a unique key which is used to identify what data is either being passed back

+  or being asked for. 

+

+Arguments:

+

+  KeyValue -        A unique value which is sent to the original exporting driver so that it

+                    can identify the type of data to expect.  The format of the data tends to

+                    vary based on the op-code that geerated the callback.

+

+  Data -            A pointer to the data being sent to the original exporting driver.
