If possible, use GDBus (part of GLib/GIO) and use functions like
g_dbus_proxy_call() and g_dbus_connection_call(), or use QtDBus and
functions like QDBusAbstractInterface::asyncCall(), or use some other
high-level library.

(I personally recommend GDBus, which uses the GAsyncResult pattern for
asynchronous calls; every function in GDBus that doesn't end with _sync
is asynchronous.)

If you have to use libdbus (the low-level reference implementation of
D-Bus), that function is the correct way to do asynchronous calls.

You will notice that that function is not particularly convenient to
use. The solution is to use a better library than libdbus.
