+<p>A <xref href="GUID-E0B34F3E-D4C4-3232-B8B1-7DB35B454646.dita"><apiname>TRequestStatus</apiname></xref> object is used to monitor the status
+and result of the asynchronous request. This object maintains the status of
+the request at various stages and finally contains the request result. The
+driver uses the status object when performing operations on the request such
+as cancelling, completing, or managing multiple similar requests. </p>
+<p>Initially, when the request is made, the Kernel changes the status to <xref href="GUID-B0778F54-C5DD-3307-A1E2-0DD339C4E4E7.dita"><apiname>KRequestPending</apiname></xref>.
+After completion of the request, the status is changed to <xref href="GUID-6AB86DE7-83FE-35AE-9528-AF9B3247E2D5.dita"><apiname>KRequestComplete</apiname></xref> to
+indicate request completion. It also contains the result of the request, which
+can indicate an error or failure of the request. <xref href="GUID-E0B34F3E-D4C4-3232-B8B1-7DB35B454646.dita#GUID-E0B34F3E-D4C4-3232-B8B1-7DB35B454646/GUID-43246976-3D7B-3B25-9C32-42E02E9ED674"><apiname>TRequestStatus::Int()</apiname></xref> returns
+the request result. </p>
