             * %G_IO_ERROR_NOT_SUPPORTED will be returned.
             *
             * As with #GInitable, if the object is not initialized, or initialization
             * returns with an error, then all operations on the object except
             * g_object_ref() and g_object_unref() are considered to be invalid, and

             * Callers should not assume that a class which implements #GAsyncInitable can

             * If a class explicitly supports being initialized multiple times,
             * implementation requires yielding all subsequent calls to init_async() on the
             * results of the first call.
             *
             * For classes that also support the #GInitable interface, the default

             * Creates a binding between `source_property` on `source` and `target_property`
             * on `target,` allowing you to set the transformation functions to be used by
             * the binding.
             *
             * If `flags` contains %G_BINDING_BIDIRECTIONAL then the binding will be mutual:
             * if `target_property` on `target` changes then the `source_property` on `source`
             * will be updated as well. The `transform_from` function is only used in case
             * of bidirectional bindings, otherwise it will be ignored
             *
             * The binding will automatically be removed when either the `source` or the
             * `target` instances are finalized. This will release the reference that is
             * being held on the #GBinding instance; if you want to hold on to the
             * #GBinding instance, you will need to hold a reference to it.
             *
             * To remove the binding, call g_binding_unbind().
             *
             * A #GObject can have multiple bindings.
             *
             * The same `user_data` parameter will be used for both `transform_to`
             * and `transform_from` transformation functions; the `notify` function will
             * be called once, when the binding is removed. If you need different data
             * for each transformation function, please use
             * g_object_bind_property_with_closures() instead.
