[dbus] The meaning of private?

[Simon Hong]

My question is started from the dbus_g_bus_get_private()  in the dbus-glib
binding.

Only dbus_g_bus_get_private() needs GMainContext, dbus_g_bus_get() don't
need.
dbus_g_bus_get() returns connections that can share.
dbus_g_bus_get_private() returns connection that cannot share because this
connection binds to GMainContext.

Does my thinking is right?

Thank you for your kind reply, Pavel.
