On every new function call, a new frame is created and pushed on topof the frame stack. To get the topmost one, use <a href="SwfdecAsContext.html#swfdec-as-context-get-frame"><code class="function">swfdec_as_context_get_frame()</code></a>. After that you can inspect various propertiesof the frame, like the current stack.</p><p>a <a href="swfdec-SwfdecAsFrame.html#SwfdecAsFrame"><span class="type">SwfdecAsFrame</span></a> is a <a href="swfdec-SwfdecAsObject.html#SwfdecAsObject"><span class="type">SwfdecAsObject</span></a>, so it is possible to set variables onit. These are local variables inside the executing function. So you can usefunctions such as <a href="swfdec-SwfdecAsObject.html#swfdec-as-object-get-variable"><code class="function">swfdec_as_object_get_variable()</code></a> to inspect them.</p><p></p></div><div class="refsect1" lang="en"><a name="id2621187"></a><h2>Details</h2><div class="refsect2" lang="en"><a name="id2621197"></a><h3><a name="SwfdecAsFrame"></a>SwfdecAsFrame</h3><a class="indexterm" name="id2621210"></a><pre class="programlisting">typedef struct _SwfdecAsFrame SwfdecAsFrame;</pre><p>the object used to represent an executing function.</p><p></p></div><hr><div class="refsect2" lang="en"><a name="id2621231"></a><h3><a name="swfdec-as-frame-get-next"></a>swfdec_as_frame_get_next ()</h3><a class="indexterm" name="id2621242"></a><pre class="programlisting"><a href="swfdec-SwfdecAsFrame.html#SwfdecAsFrame">SwfdecAsFrame</a>* swfdec_as_frame_get_next (<a href="swfdec-SwfdecAsFrame.html#SwfdecAsFrame">SwfdecAsFrame</a> *frame);</pre><p>Gets the next frame in the frame stack.
