+<p>Because media drivers are implemented as kernel extensions, use the <xref href="GUID-F10BBEC9-FC49-3B85-9B7F-9A6DB66A7B30.dita"><apiname>DECLARE_EXTENSION_PDD()</apiname></xref> macro
+as a wrapper around the code that creates your factory object; the following
+code fragment is typical: </p>

+    {
+    return new DMyPhysicalDevice;
+    } </codeblock>
+<p>where <codeph>DMyPhysicalDevice</codeph> is an implementation of <xref href="GUID-A5484A7F-94B9-34C7-9F88-82B1BF516930.dita"><apiname>DPhysicalDevice</apiname></xref>. </p>
