+ * @probability: The probability in percent that the suggestion is right
+ * @media_type: the media type of the suggested caps
+ * @fieldname: first field of the suggested caps, or NULL
+ * @...: additional arguments to the suggested caps in the same format as the
+ *     arguments passed to gst_structure_new() (ie. triplets of field name,
+ *     field GType and field value)
+ *
+ * If a #GstTypeFindFunction calls this function it suggests the caps with the
+ * given probability. A #GstTypeFindFunction may supply different suggestions
+ * in one call. It is up to the caller of the #GstTypeFindFunction to interpret
+ * these values.
+ *
+ * This function is similar to gst_type_find_suggest(), only that instead of
+ * passing a #GstCaps argument you can create the caps on the fly in the same
+ * way as you can with gst_caps_new_simple().
+ *
+ * Make sure you terminate the list of arguments with a NULL argument and that
+ * the values passed have the correct type (in terms of width in bytes when
+ * passed to the vararg function - this applies particularly to gdouble and
+ * guint64 arguments).
