Name of method to invoke.
A #GVariant tuple with parameters for the signal or %NULL if not passing parameters.
Flags from the #GDBusCallFlags enumeration.
The timeout in milliseconds (with %G_MAXINT meaning "infinite") or -1 to use the proxy default timeout.
A #GCancellable or %NULL.
A #GAsyncReadyCallback to call when the request is satisfied or %NULL if you don't care about the result of the method invocation.
The data to pass to @callback.

Asynchronously invokes the @method_name method on @proxy.
If @method_name contains any dots, then @name is split into interface and method name parts. This allows using @proxy for invoking methods on other interfaces.
If the #GDBusConnection associated with @proxy is closed then the operation will fail with %G_IO_ERROR_CLOSED. If @cancellable is canceled, the operation will fail with %G_IO_ERROR_CANCELLED. If @parameters contains a value not compatible with the D-Bus protocol, the operation fails with %G_IO_ERROR_INVALID_ARGUMENT.
If the @parameters #GVariant is floating, it is consumed. This allows convenient 'inline' use of g_variant_new(), e.g.: |[<!-- language="C" --> g_dbus_proxy_call (proxy, "TwoStrings", g_variant_new ("(ss)", "Thing One", "Thing Two"), G_DBUS_CALL_FLAGS_NONE, -1, NULL, (GAsyncReadyCallback) two_strings_done, &data); ]|
If @proxy has an expected interface (see #GDBusProxy:g-interface-info) and @method_name is referenced by it, then the return value is checked against the return type.
This is an asynchronous method. When the operation is finished, @callback will be invoked in the [thread-default main context][g-main-context-push-thread-default] of the thread you are calling this method from. You can then call g_dbus_proxy_call_finish() to get the result of the operation. See g_dbus_proxy_call_sync() for the synchronous version of this method.
If @callback is %NULL then the D-Bus method call message will be sent with the %G_DBUS_MESSAGE_FLAGS_NO_REPLY_EXPECTED flag set.
