#### 介绍
P2P模式：这种模式一般称之为点对点的星型结构，Client与Server之间是直接的Peer2Peer的连接，少了DBus Daemon的中转，因此性能较好。

#### 软件架构
server结构

//创建loop，不运行
    pLoop = g_main_loop_new(NULL, FALSE);
    //创建skeleton
    pSkeleton = rtplay_gdbus_example_skeleton_new();
    //获得guid
    _guid = g_dbus_generate_guid();
    //创建一个新的D-Bus服务器，该服务器侦听有效address中的第一个地址。
    _server = g_dbus_server_new_sync("unix:abstract=gdbus_server", G_DBUS_SERVER_FLAGS_AUTHENTICATION_ALLOW_ANONYMOUS, _guid, NULL, NULL, &_error);
    //注册new-connection，在客户端链接时被调用
    g_signal_connect(_server, "new-connection", G_CALLBACK(on_new_connection), NULL);
    //启动server。
    g_dbus_server_start(_server);
    //运行loop
    g_main_loop_run(pLoop);

on_new_connection函数

//获得_iface
    _iface = RTPLAY_GDBUS_EXAMPLE_GET_IFACE(pSkeleton);
    //注册方法，当客户端调用时会被执行
    _iface->handle_my_method1 = My_Method1;
    //导出interface，获得connection。
    g_dbus_interface_skeleton_export(G_DBUS_INTERFACE_SKELETON(pSkeleton), connection, RTPLAY_GDBUS_EXAMPLE_OBJECT_PATH, &_error);
    //注册closed，在客户端断开时被调用
    g_signal_connect(connection, "closed", G_CALLBACK(on_close_connection), user_data);

client结构

//创建loop，不运行
    pLoop = g_main_loop_new(NULL, FALSE);
    //同步连接并建立D-Bus客户端连接，以与由地址指定的端点交换D-Bus消息。
    _pGdbus_connection = g_dbus_connection_new_for_address_sync("unix:abstract=gdbus_server", G_DBUS_CONNECTION_FLAGS_AUTHENTICATION_CLIENT, NULL, NULL, &_pError);
    //创建proxy，链接信号使用
    pProxy = rtplay_gdbus_example_proxy_new_sync(_pGdbus_connection, G_DBUS_PROXY_FLAGS_NONE, NULL, RTPLAY_GDBUS_EXAMPLE_OBJECT_PATH, NULL, &_pError);
    //信号链接
    g_signal_connect(pProxy, "my-signal1", G_CALLBACK(My_Signal_1_Handler), NULL);
    //运行loop
    g_main_loop_run(pLoop);
