Helper function for constructing GAsyncInitable object. This is similar to g_object_newv() 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.
the number of parameters in parameters
the parameters to use to construct the object
the [I/O priority][io-priority] of the operation
optional gio.Cancellable object, NULL to ignore.
a GAsyncReadyCallback to call when the initialization is finished
the data to pass to callback function
Deprecated: Use g_object_new_with_properties() and g_async_initable_init_async() instead. See GParameter for more information.
