+<p>On completion of the request, the driver calls <xref href="GUID-C6946ECB-775F-3EC2-A56F-78F25B9FBE3D.dita#GUID-C6946ECB-775F-3EC2-A56F-78F25B9FBE3D/GUID-D720BB4C-5E31-3213-BB16-859AA325FE98"><apiname>Kern::RequestComplete()</apiname></xref>,
+passing the <codeph>TRequestStatus</codeph> object and completion error code,
+to notify the request completion to the user. This API internally sets the
+passed error code in the <codeph>TRequestStatus</codeph> object. It also signals
+the client's thread semaphore. </p>
