+construct an iterator</title><shortdesc>An iterator allows you to access each element of the list in turn.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>To create an iterator for a singly linked list of <codeph>CMyClass</codeph> elements,
+defined as:</p>
+<codeblock id="GUID-AFE2C594-F211-52E6-9378-4327A6AFD667" xml:space="preserve">class CMyClass : public CBase
+    {
+    ...
+    TSglQueLink iSlink;
+    ...
+    };</codeblock>
+<p>first construct a <xref href="GUID-2364CAB0-E19E-5EBB-837F-F6484642C2E4.dita">Header</xref>:</p>
+<codeblock id="GUID-9EE3B51E-75D0-5F2E-921B-695E3FB55672" xml:space="preserve">TSglQue&lt;CMyClass&gt; queHeader(_FOFF(CMyClass,iSlink));</codeblock>
+<p> and then construct the <xref href="GUID-82C53275-6F7C-5B3D-9A07-FA4801D42403.dita">Iterator</xref>.
+The iterator requires the header at construction time but the list can be
+empty:</p>
+<codeblock id="GUID-0E4BEBDA-2EF2-5D6C-84D8-1CE1BCCCF00D" xml:space="preserve">TSglQueIter&lt;CMyClass&gt; queIter(queHeader);</codeblock>
+<p>The <codeph>TSglQueIter</codeph> class takes a class template parameter
+that defines the type of object which is to form an element of the list.</p>
