先看下server-socket的事件：

SOCKET_ACCEPT   仅服务端，accept成功,还需要start
SOCKET_OPEN     连接建立并处于工作状态
SOCKET_DATA     有数据
SOCKET_CLOSE    连接关闭
SOCKET_ERROR    发生错误
SOCKET_EXIT     退出事件

下面是server-socket接口：

接口                            描述
socket\_server\_create        创建socket_server
socket\_server\_release       销毁socket_server
socket\_server\_poll          获取socket事件，事件类型如上所述
socket\_server\_exit          发送SOCKET_EXIT事件，表示逻辑循环退出
socket\_server\_close         主动关闭socket，会触发SOCKET_CLOSE事件
socket\_server\_listen        仅服务端，监听,socket, bind, listen
socket\_server\_start         仅服务端，启动socket，调用该函数后socket才可以接收发送数据
socket\_server\_send          发送消息
socket\_server\_connect       非阻塞的方式连接
socket\_server\_block_connect 以阻塞方式连接
socket\_server\_bind          将stdin、stdout等FD加入到管理

skynet的socket接口对应：
