/**
 * The #GDBusConnection type is used for D-Bus connections to remote
 * peers such as a message buses. It is a low-level API that offers a
 * lot of flexibility. For instance, it lets you establish a connection
 * over any transport that can by represented as a #GIOStream.
 * 
 * This class is rarely used directly in D-Bus clients. If you are writing
 * a D-Bus client, it is often easier to use the g_bus_own_name(),
 * g_bus_watch_name() or g_dbus_proxy_new_for_bus() APIs.
 * 
 * As an exception to the usual GLib rule that a particular object must not
 * be used by two threads at the same time, #GDBusConnection's methods may be
 * called from any thread. This is so that g_bus_get() and g_bus_get_sync()
 * can safely return the same #GDBusConnection when called from any thread.
 * 
 * Most of the ways to obtain a #GDBusConnection automatically initialize it
 * (i.e. connect to D-Bus): for instance, g_dbus_connection_new() and
 * g_bus_get(), and the synchronous versions of those methods, give you an
 * initialized connection. Language bindings for GIO should use
 * g_initable_new() or g_async_initable_new_async(), which also initialize the
 * connection.
 * 
 * If you construct an uninitialized #GDBusConnection, such as via
 * g_object_new(), you must initialize it via g_initable_init() or
 * g_async_initable_init_async() before using its methods or properties.
 * Calling methods or accessing properties on a #GDBusConnection that has not
 * completed initialization successfully is considered to be invalid, and leads
 * to undefined behaviour. In particular, if initialization fails with a
 * #GError, the only valid thing you can do with that #GDBusConnection is to
 * free it with g_object_unref().
 *

 * 
 * Here is an example for a D-Bus server:
 * [gdbus-example-server.c](https://git.gnome.org/browse/glib/tree/gio/tests/gdbus-example-server.c)

	 * This is a synchronous failable function. See g_bus_get() and

	 * event that you need a private message bus connection, use
	 * g_dbus_address_get_for_bus_sync() and
	 * g_dbus_connection_new_for_address().
	 *
	 * Note that the returned #GDBusConnection object will (usually) have
	 * the #GDBusConnection:exit-on-close property set to %TRUE.
