-Routine Description:\r
-\r
- This is the function that is called to provide results data to the driver. This data\r
- consists of a unique key which is used to identify what data is either being passed back\r
- or being asked for. \r
-\r
-Arguments:\r
-\r
- KeyValue - A unique value which is sent to the original exporting driver so that it\r
- can identify the type of data to expect. The format of the data tends to\r
- vary based on the op-code that geerated the callback.\r
-\r
- Data - A pointer to the data being sent to the original exporting driver.\r
