+ *
+ * This is a version of g_file_enumerator_next_file() that's easier to
+ * use correctly from C programs.  With g_file_enumerator_next_file(),
+ * the gboolean return value signifies "end of iteration or error", which
+ * requires allocation of a temporary #GError.
+ *
+ * In contrast, with this function, a %FALSE return from
+ * gs_file_enumerator_iterate() *always* means
+ * "error".  End of iteration is signaled by @out_info or @out_child being %NULL.
+ *
+ * Another crucial difference is that the references for @out_info and
+ * @out_child are owned by @direnum (they are cached as hidden
+ * properties).  You must not unref them in your own code.  This makes
+ * memory management significantly easier for C code in combination
+ * with loops.
+ *
+ * Finally, this function optionally allows retrieving a #GFile as
+ * well.
+ *
+ * You must specify at least one of @out_info or @out_child.
+ *
+ * The code pattern for correctly using g_file_enumerator_iterate() from C
+ * is:
