                          OwrMessageSubType sub_type,
                          GHashTable *data,
                          gpointer user_data);

Parameters

origin

the origin of the message, an OwrMessageOrigin.

[transfer none]

type

the OwrMessageType of the message

  

sub_type

the OwrMessageSubType of the message

  

data

the data passed to owr_bus_set_message_callback.

[element-type utf8 GValue][nullable][transfer none]

user_data

the data passed to owr_bus_set_message_callback.

owr_bus_new ()

OwrBus *
owr_bus_new ();

owr_bus_set_message_callback ()

void
owr_bus_set_message_callback (OwrBus *bus,
                              OwrBusMessageCallback callback,
                              gpointer user_data,
                              GDestroyNotify destroy_data);

Parameters

bus

an OwrBus

  

callback

(scope notified)

  

user_data

user data for callback .

[nullable]

destroy_data

a GDestroyNotify for user_data .

owr_bus_add_message_origin ()

void
owr_bus_add_message_origin (OwrBus *bus,
                            OwrMessageOrigin *origin);

Adds a message origin to the bus, adding an already existing message origin has no effect.

origin

the message origin that is added to the bus.

[transfer none]

owr_bus_remove_message_origin ()

void
owr_bus_remove_message_origin (OwrBus *bus,
                               OwrMessageOrigin *origin);
