### Function

# Gio AsyncInitablenew_async

since: 2.22

#### Declaration [src]

    void
    g_async_initable_new_async (
      GType object_type,
      int io_priority,
      GCancellable* cancellable,
      GAsyncReadyCallback callback,
      gpointer user_data,
      const gchar* first_property_name,
      ...
    )

#### Description [src]

Helper function for constructing `GAsyncInitable` object. This is similar to `g_object_new()` but also initializes the object asynchronously.

When the initialization is finished, `callback` will be called. You can then call `g_async_initable_new_finish()` to get the new object and check for any errors.

Available since: 2.22

This function is not directly available to language bindings.
