+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
