<DT><B>dwForwardSize</B> </DT>
<DT><B>dwForwardOffset</B> </DT>
<DD>The size, in bytes, and the offset, in bytes, from the beginning of this data structure of the variably sized field that describes the address's forwarding information. This information is an array of <B>dwForwardNumEntries</B> elements, of type <A HREF="struc2_781e.htm" tppabs="http://msdn.microsoft.com/library/psdk/tapi22/struc2_781e.htm"><B>LINEFORWARD</B></A>.

<DD>The size, in bytes, and the offset, in bytes, from the beginning of this data structure of the variably sized device-specific field.
</DD>
</DL>
<H4>Remarks</H4>
<P>Device-specific extensions should use the <B>DevSpecific </B>(<B>dwDevSpecificSize</B> and <B>dwDevSpecificOffset</B>) variably sized area of this data structure. </P>
