<p>It is possible to iterate over all the <a class="link" href="ClutterPath.html#ClutterPathNode"><span class="type">ClutterPathNode</span></a>s
inside a <a class="link" href="ClutterPath.html" title="ClutterPath"><span class="type">ClutterPath</span></a> by using <a class="link" href="ClutterPath.html#clutter-path-get-nodes" title="clutter_path_get_nodes ()"><code class="function">clutter_path_get_nodes()</code></a>, which will return
a <span class="type">GSList</span> of <a class="link" href="ClutterPath.html#ClutterPathNode"><span class="type">ClutterPathNode</span></a>s; or by using <a class="link" href="ClutterPath.html#clutter-path-foreach" title="clutter_path_foreach ()"><code class="function">clutter_path_foreach()</code></a>
with a function.</p>
<p>The function pointer passed to <a class="link" href="ClutterPath.html#clutter-path-foreach" title="clutter_path_foreach ()"><code class="function">clutter_path_foreach()</code></a> should have the
following definition:</p>
