㈠ 求C++，socket聊天程序的代码，最好是实现了两个客户端之间经由服务器的信息互发，聊天功能要完整些

㈡ 这段socket代码的注释 谁给加点详细注释啊 谢谢
要分好几次发送，第一次还没发完就回调了，在回调函数中再来第二次发送不就出异常了）。
2.数据接收完毕或者缓冲区满了时。（如果没有数据发过来，这个线程会一直挂起，没有“超过某个时间就回调”的说法）。
3.数据发送完毕和关闭Socket有什么联系呢,数据发送完了,Socket连接还在呀, 除非你调用了Socket.ShutDown(SocketShutdown.Both)时就不能收发数据了，Socket.Close()才会关闭Socket，Socket的关闭是由你来控制的。
例子：（随便写了几句代码，给你加点注释）
int i;
int size = 1024;
byte buffer = new byte[size];
//读文件
FileStream fs =new FileStream(filename,FileMode.Open,FileAccess.Read);
//将文件转化成二进制流(不然怎么传)
BinaryReader br = new BinaryReader(fs);
Socket sock = new Socket(AddressFamily.InterNetwork,
SocketType.Stream, ProtocolType.Tcp);
//连接对方主机的ip地址和侦听端口
sock.Connect(ip, port);
//将文件的二进制流读入缓冲区
br.Read(buffer, 0, size);
//将缓冲区的内容异步发送出去，委托回调函数EndSendFile()在后面
sock.BeginSend(buffer, 0, size, SocketFlags.None,
new AsyncCallback(EndSendFile), null);
private void EndSendFile(IAsyncResult AR)
{
//结束挂起的异步发送
sock.EndSend(AR);
//判断文件是否读完，没读完继续读到缓冲区
if ((i = br.Read(buffer, 0, size)) != 0)
{
//发送缓冲区内容，你看清楚回调函数(就是本函数)
//就是说这次发送完后又调用这个函数来判断和发送
sock.BeginSend(buffer, 0, size, SocketFlags.None,
new AsyncCallback(EndSendFile), null);
}
}
这是我随便写的几句代码，不过我以前都实践过的，应该是对的，你想运行它的话，还要自己加点东西，还要写个接收程序(异步接收的话就用你说的BeginReceive()试一试)。
另外,团IDC网上有许多产品团购,便宜有口碑
㈢ 求实现基于java Socket网络通信的客户端和服务器端的源代码。
服务器端Server.java: import java.io.*;import java.net.*; public class Server{ publicstatic void main(String[] args) { try{ ServerSocket s = newServerSocket(9000); while (true) { Socket incoming =s.accept(); try { FileInputStreamfstream = new FileInputStream("Server.java"); //假设输入文件为Server.java DataInputStream in =new DataInputStream(fstream); BufferedReaderbr = new BufferedReader(new InputStreamReader(in)); OutputStreamostream = incoming.getOutputStream(); PrintWriterout = new PrintWriter(ostream, true); String strLine; while ((strLine =br.readLine()) != null) { out.println(strLine); } in.close(); } finally { incoming.close(); } } }catch (Exception e){ e.printStackTrace(); } }} 客户端Client.java: import java.io.*;import java.net.*;import java.util.*; public class Client{ publicstatic void main(String[] args) { try { Sockets = new Socket("localhost", 9000); try { InputStreaminStream = s.getInputStream(); Scannerin = new Scanner(inStream); PrintWriter out = newPrintWriter("test.txt");//假设输出文件为test.txt while(in.hasNextLine()) { Stringline = in.nextLine(); System.out.println(line); out.println(line); } out.close(); } finally { s.close(); } } catch(IOException e) { e.printStackTrace(); } }}
㈣ 如何安装luasocket源码
第一种方法：如果你有安装了 Lua 模块的安装和部署工具 LuaRocks，那么一条指令就能安装部署好 LuaSocket：
# luarocks install luasocket
第二种方法：如果没安装有 LuaRocks，也可以源码安装。
先把 LuaRocks 下载下来，当前可用的版本是 luasocket-3.0-rc1（luasocket的源码有托管在Github.com）：
# git clone https://github.com/diegonehab/luasocket.git
把源码clone下来之后就可以进行本地源码安装，直接进入到luasocket目录进行编译安装了
# cd luasocket
# make && make install
㈤ 求一个socket聊天程序源码 C语言的
通过socket编程自己写一个呗，可以学习一下socket编程方面的知识
㈥ 如何运行socket 代码
呵呵 这个工具刚刚用过 SocketTool
这个是windows下面的，可以装在windows下面，分别测试你linux的客户端和服务端
有邮箱的话 我发给你
㈦ 如何看javawebsocket源码
import java.io.IOException;
import java.io.InputStream;
import javax.websocket.OnClose;
import javax.websocket.OnError;
import javax.websocket.OnOpen;
import javax.websocket.Session;
import javax.websocket.server.ServerEndpoint;
@ServerEndpoint("/log")
public class LogWebSocketHandle {
private Process process;
private InputStream inputStream;
/**
* 新的WebSocket请求开启
*/
@OnOpen
public void onOpen(Session session) {
try {
// 执行tail -f命令
process = Runtime.getRuntime().exec("tail -f /var/log/syslog");
inputStream = process.getInputStream();
// 一定要启动新的线程，防止InputStream阻塞处理WebSocket的线程
TailLogThread thread = new TailLogThread(inputStream, session);
thread.start();
} catch (IOException e) {
e.printStackTrace();
}
}
/**
* WebSocket请求关闭
*/
@OnClose
public void onClose() {
try {
if(inputStream != null)
inputStream.close();
} catch (Exception e) {
e.printStackTrace();
}
if(process != null)
process.destroy();
}
@OnError
public void onError(Throwable thr) {
thr.printStackTrace();
}
}
㈧ socket编程问题（附代码）
1.首先你的程序时是单线程的程序。
2.基于SOCKET的程序，也就是C/S程序，要区分那个是C,那个是S。
3.建议你看下孙鑫的VC++视频里面的基于SOCKET通信。

㈩ 在那里可以看到socket()函数的源代码
这是微软的机密，没有向我们提供，只提供了头文件。
还有你的基础不好，要努力啊。
include只会包含头文件，一般是.h
如果你要看类似的代码，可以去www.freebsd.org.cn的服务器下载freeBSD的源代码慢慢看。（socket是谁发明的，我想你知道吧。)
建设性的建议：看看
