+  /* Virtual table implementations will typically add additional fields */
+};

+<p>
+Every <a href="../c3ref/module.html">virtual table module</a> implementation uses a subclass of the
+following structure to describe cursors that point into the
+<a href="../vtab.html">virtual table</a> and are used
+to loop through the virtual table.  Cursors are created using the
+<a href="../vtab.html#xopen">xOpen</a> method of the module and are destroyed
+by the <a href="../vtab.html#xclose">xClose</a> method.  Cursors are used
+by the <a href="../vtab.html#xfilter">xFilter</a>, <a href="../vtab.html#xnext">xNext</a>, <a href="../vtab.html#xeof">xEof</a>, <a href="../vtab.html#xcolumn">xColumn</a>, and <a href="../vtab.html#xrowid">xRowid</a> methods
+of the module.  Each module implementation will define
+the content of a cursor structure to suit its own needs.</p>
+
+<p>This superclass exists in order to define fields of the cursor that
+are common to all implementations.
