From 39dd1fcee640b4a5a9abb453a9ccd5b7e099ba1c Mon Sep 17 00:00:00 2001 From: Anders Carlsson Date: Sat, 25 Jan 2003 20:53:53 +0000 Subject: 2003-01-25 Anders Carlsson * bus/Makefile.am: * bus/connection.c: (connection_disconnect_handler), (connection_watch_callback), (bus_connection_setup): * bus/dispatch.c: (send_one_message), (bus_dispatch_broadcast_message), (bus_dispatch_message_handler), (bus_dispatch_add_connection), (bus_dispatch_remove_connection): * bus/dispatch.h: * bus/driver.c: (bus_driver_send_service_deleted), (bus_driver_send_service_created), (bus_driver_handle_hello), (bus_driver_send_welcome_message), (bus_driver_handle_list_services), (bus_driver_remove_connection), (bus_driver_handle_message): * bus/driver.h: Refactor code, put the message dispatching in its own file. Use _DBUS_HANDLE_OOM. Also send ServiceDeleted messages when a client is disconnected. --- bus/dispatch.c | 126 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 126 insertions(+) create mode 100644 bus/dispatch.c (limited to 'bus/dispatch.c') diff --git a/bus/dispatch.c b/bus/dispatch.c new file mode 100644 index 00000000..a74b3719 --- /dev/null +++ b/bus/dispatch.c @@ -0,0 +1,126 @@ +/* -*- mode: C; c-file-style: "gnu" -*- */ +/* dispatch.c Message dispatcher + * + * Copyright (C) 2003 CodeFactory AB + * + * Licensed under the Academic Free License version 1.2 + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
