-/**
- * SECTION:gsttrace
- * @short_description: Tracing functionality
- *
- * Traces allows to track object allocation. They provide a instance counter per
- * #GType. The counter is incremented for each object allocated and decremented
- * it when it's freed.
- *
- * <example>
- * <title>Tracing object instances</title>
- * <programlisting>
- * // trace un-freed object instances
- * gst_alloc_trace_set_flags_all (GST_ALLOC_TRACE_LIVE);
- * if (!gst_alloc_trace_available ()) {
- * g_warning ("Trace not available (recompile with trace enabled).");
- * }
- * gst_alloc_trace_print_live ();
- * // do something here
- * gst_alloc_trace_print_live ();
- * </programlisting>
- * </example>
- *
- * Last reviewed on 2005-11-21 (0.9.5)
