- * <title>Filtering a list</title>
- * <programlisting>
- * GList *node;
- * GstObject *result = NULL;
- *
- * node = gst_filter_run (list, (GstFilterFunc) my_filter, TRUE, NULL);
- * if (node) {
- * result = GST_OBJECT (node->data);
- * gst_object_ref (result);

-/**
- * gst_filter_run:
- * @list: a linked list
- * @func: (scope call): the function to execute for each item
- * @first: flag to stop execution after a successful item
- * @user_data: (closure): user data
- *
- * Iterates over the elements in @list, calling @func with the
- * list item data for each item. If @func returns TRUE, @data is
- * prepended to the list of results returned. If @first is true,
- * the search is halted after the first result is found.
- *
- * Since gst_filter_run() knows nothing about the type of @data, no
- * reference will be taken (if @data refers to an object) and no copy of
- * @data wil be made in any other way when prepending @data to the list of
- * results.
- *
- * Returns: (transfer container): the list of results. Free with g_list_free()
- * when no longer needed (the data contained in the list is a flat copy
- * and does need to be unreferenced or freed).
