Net::DBus::Binding::Bus − Handle to a well−known message bus instance


  use Net::DBus::Binding::Bus;
  # Get a handle to the system bus
  my $bus = Net::DBus::Binding::Bus−>new(type => &Net::DBus::Binding::Bus::SYSTEM);


This is a specialization of the Net::DBus::Binding::Connection module providing convenience constructor for connecting to one of the well-known bus types. There is no reason to use this module directly, instead get a handle to the bus with the "session" or "system" methods in Net::DBus.


my $bus = Net::DBus::Binding::Bus−>new(type => $type);
my $bus = Net::DBus::Binding::Bus−>new(address => $addr);

Open a connection to a message bus, either a well known bus type specified using the "type" parameter, or an arbitrary bus specified using the "address" parameter. If the "private" parameter is set to a true value, then a private connection to the bus is obtained. The caller must explicitly disconnect this bus instance before releasing the last instance of the object.


Send a request to the bus registering the well known name specified in the $service_name parameter. If another client already owns the name, registration will be queued up, pending the exit of the other client.

my $name = $bus−>get_unique_name

Returns the unique name by which this processes’ connection to the bus is known. Unique names are never re-used for the entire lifetime of the bus daemon.


Register a signal match rule with the bus controller, allowing matching broadcast signals to routed to this client.


Unregister a signal match rule with the bus controller, preventing further broadcast signals being routed to this client
