Function

Giobus_get_sync

Declaration [src]

GDBusConnection*
g_bus_get_sync (
  GBusType bus_type,
  GCancellable* cancellable,
  GError** error
)

Description [src]

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 g_bus_get() and g_bus_get_finish() for the asynchronous version.

The returned object is a singleton, that is, shared with other callers of g_bus_get() and g_bus_get_sync() for bus_type. In the event that you need a private message bus connection, use g_dbus_address_get_for_bus_sync() and g_dbus_connection_new_for_address().

Note that the returned GDBusConnection object will (usually) have the GDBusConnection:exit-on-close property set to TRUE.
