The background is that a process normally only has a single connection
to the bus. Even if you call dbus_bus_get several times at different
places in your code -- or concurrently in threads --, libdbus will
always return the same connection. Thus, its named shared connection.
When dbus_bus_get_private is being called you get a private connection
which is not being shared.
Most of the time we're talking about shared connections, not private
ones (in D-Bus terms spoken). You should never call
dbus_connection_close on such a shared connection. If a part of your
application does no longer require a D-Bus connection, simply unref it
(dbus_connection_unref) and you're done. You must not call
That's why closing a shared connection shall not be done but is alright
for a private connection.
