Hi, I developped a code, which use dbus, I inserted in my code an introspection, but while running it I obtain an error of segmentation<br>this is a part of code where is the problem:<br>             static const char introspect_xml[] =<br>
          &quot;&lt;!DOCTYPE node PUBLIC \&quot;-//freedesktop//DTD D-BUS Object Introspection 1.0//EN\&quot;\n&quot;<br>          &quot;                      \&quot;<a href="http://www.freedesktop.org/standards/dbus/1.0/introspect.dtd">http://www.freedesktop.org/standards/dbus/1.0/introspect.dtd</a>\&quot;&gt;\n&quot;<br>
          &quot;&lt;node&gt;\n&quot;<br>          &quot;  &lt;interface name=\&quot;ch.cett.misse.ffmpeg\&quot;&gt;\n&quot;<br>          &quot;    &lt;method name=\&quot;image_rate_get\&quot;&gt;\n&quot;<br>          &quot;      &lt;arg name=\&quot;port\&quot; direction=\&quot;out\&quot; type=\&quot;u\&quot;/&gt;\n&quot;<br>
          &quot;    &lt;/method&gt;\n&quot;<br>          &quot;  &lt;/interface&gt;\n&quot;<br>          &quot;&lt;/node&gt;\n&quot;;<br>        reply = dbus_message_new_method_return(msg);<br>               if (!dbus_message_append_args (reply,<br>
                                 DBUS_TYPE_STRING, &amp;introspect_xml,<br>                                 DBUS_TYPE_INVALID))<br>        {<br>              fprintf(stderr, &quot;Out Of Memory!\n&quot;);<br>              exit(1);<br>
        }<br><br>        if (!dbus_connection_send(conn, reply, &amp;serial)) <br>        {<br>              fprintf(stderr, &quot;Out Of Memory!\n&quot;);<br>              exit(1);<br>           }<br><br>I think the problem is with DBUS_TYPE_STRING, which type I have to use<br>
thank you<br>
