Function gio::bus_get_sync
source · pub fn bus_get_sync(
bus_type: BusType,
cancellable: Option<&impl IsA<Cancellable>>
) -> Result<DBusConnection, Error>
Expand description
Synchronously connects to the message bus specified by bus_type
.
Note that the returned object may shared with other callers,
e.g. if two separate parts of a process calls this function with
the same bus_type
, they will share the same object.
This is a synchronous failable function. See bus_get()
and
g_bus_get_finish()
for the asynchronous version.
The returned object is a singleton, that is, shared with other
callers of bus_get()
and bus_get_sync()
for bus_type
. In the
event that you need a private message bus connection, use
dbus_address_get_for_bus_sync()
and
DBusConnection::for_address()
with
G_DBUS_CONNECTION_FLAGS_AUTHENTICATION_CLIENT and
G_DBUS_CONNECTION_FLAGS_MESSAGE_BUS_CONNECTION flags.
Note that the returned DBusConnection
object will (usually) have
the property::DBusConnection::exit-on-close
property set to true
.
bus_type
a BusType
cancellable
a Cancellable
or None
Returns
a DBusConnection
or None
if error
is set.
Free with g_object_unref()
.
