<DIV>Hi, everyone.</DIV>
<DIV>I&nbsp;would like to use gstreamer singals to get some running&nbsp;parameters, but&nbsp;I don't know how to use</DIV>
<DIV>them in my&nbsp;project. For example:</DIV>
<DIV>&nbsp;&nbsp;&nbsp; I got a signal named "get-stats" in multiudpsink, and it is defined like this:</DIV>
<DIV><PRE class="programlisting">GValueArray*user_function                  (<A href="http://gstreamer.freedesktop.org/data/doc/gstreamer/0.10.2/gst-plugins-good-plugins/html/gst-plugins-good-plugins-multiudpsink.html#GstMultiUDPSink">GstMultiUDPSink</A> *gstmultiudpsink,
                                            gchar *host,
                                            gint port,
                                            gpointer user_data);</PRE>
<P>Get the statistics of the client with destination <EM class="parameter"><CODE><FONT face="NSimsun">host</FONT></CODE></EM> and <EM class="parameter"><CODE><FONT face="NSimsun">port</FONT></CODE></EM>.</P>

<DIV class="variablelist">My question is when I use this signal with g_signal_emit_by_name, how to return the GValueArray Object, where is it stored? Or any other better ways?</DIV>
<DIV class="variablelist">Can anybody give me some help.</DIV>
