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.
Returns:
