524 * @user_data: User data to pass to handlers.
525 * @user_data_free_func: Function for freeing @user_data or %NULL.
527 * Starts acquiring @name on the bus specified by @bus_type and calls
528 * @name_acquired_handler and @name_lost_handler when the name is
529 * acquired respectively lost. Callbacks will be invoked in the <link
530 * linkend="g-main-context-push-thread-default">thread-default main
531 * loop</link> of the thread you are calling this function from.
533 * You are guaranteed that one of the @name_acquired_handler and @name_lost_handler
534 * callbacks will be invoked after calling this function - there are three
538 * @name_lost_handler with a %NULL connection (if a connection to the bus can't be made).
541 * @bus_acquired_handler then @name_lost_handler (if the name can't be obtained)
544 * @bus_acquired_handler then @name_acquired_handler (if the name was obtained).
547 * When you are done owning the name, just call g_bus_unown_name()
548 * with the owner id this function returns.
550 * If the name is acquired or lost (for example another application
551 * could acquire the name if you allow replacement or the application
552 * currently owning the name exits), the handlers are also invoked. If the
553 * #GDBusConnection that is used for attempting to own the name
554 * closes, then @name_lost_handler is invoked since it is no
555 * longer possible for other processes to access the process.
557 * You cannot use g_bus_own_name() several times for the same name (unless
558 * interleaved with calls to g_bus_unown_name()) - only the first call
561 * Another guarantee is that invocations of @name_acquired_handler
562 * and @name_lost_handler are guaranteed to alternate; that
563 * is, if @name_acquired_handler is invoked then you are
564 * guaranteed that the next time one of the handlers is invoked, it
565 * will be @name_lost_handler. The reverse is also true.
567 * If you plan on exporting objects (using e.g.
568 * g_dbus_connection_register_object()), note that it is generally too late
569 * to export the objects in @name_acquired_handler. Instead, you can do this
570 * in @bus_acquired_handler since you are guaranteed that this will run
571 * before @name is requested from the bus.
573 * This behavior makes it very simple to write applications that wants
574 * to own names and export objects, see <xref linkend="gdbus-owning-names"/>.
575 * Simply register objects to be exported in @bus_acquired_handler and
576 * unregister the objects (if any) in @name_lost_handler.
578 * Returns: An identifier (never 0) that an be used with
579 * g_bus_unown_name() to stop owning the name.
