一个基于boost 库 asio 的聊天程序,该怎么解决

一个基于boost 库 asio 的聊天程序
一个基于boost 库 asio 的聊天程序，我在服务器端知道 客户端的IP地址 怎么向每个客户端发送数据  比如说 我在服务器端有10 客服端的IP地址   怎么把一条数据发送给这10个客户端？？

服务器端源代码如下：

#include "stdafx.h"
#include <boost/asio.hpp>
#include <boost/bind.hpp>
#include <boost/shared_ptr.hpp>
#include <boost/enable_shared_from_this.hpp>
#include <iostream>
using boost::asio::ip::tcp;
using namespace std;
#define max_len 1024
string  stIp[100];
class clientSession:public boost::enable_shared_from_this<clientSession>
{
   public:
      tcp::socket m_socket;
      char bufRec[max_len];
  char bufSed[max_len];
  
  typedef boost::shared_ptr<clientSession> session_ptr;
   public:
     clientSession(boost::asio::io_service& ioservice):m_socket(ioservice)
     {
        memset(bufRec,0,sizeof(bufRec));
memset(bufSed,0,sizeof(bufSed));
for(int i=0;i<100;i++)
    {
      stIp[i]="";
    }
     }
     ~clientSession()
     {}
     tcp::socket& socket()
     {
       return m_socket;
     }
     void start()
     {
   m_socket.async_read_some(boost::asio::buffer(bufRec,max_len),
                                boost::bind(&clientSession::handle_read,shared_from_this(),
                                            boost::asio::placeholders::error)
);
   boost::asio::async_write(m_socket,
                                boost::asio::buffer("link successed!"),
                                boost::bind(&clientSession::handle_write,shared_from_this(),
                                            boost::asio::placeholders::error)
               );
     }
   private:
     void handle_write(const boost::system::error_code& error)
     {
        if(error)
        {
          m_socket.close();
        }
for(int i=0;i<100,!stIp[i].empty();i++)      //在 这里实现 向各个客户端发送某个客户端所说的话
{
m_socket.remote_endpoint().address().from_string(stIp[i].c_str());
boost::asio::async_write(m_socket,
                                     boost::asio::buffer(bufRec),
                                     boost::bind(&clientSession::handle_write,shared_from_this(),
                                                 boost::asio::placeholders::error)
               );
}
     }
     void handle_read(const boost::system::error_code& error)
     {
        if(!error)
        {
  
  cout <<m_socket.remote_endpoint().address()<<"  say :  "<< bufRec << endl;
          m_socket.async_read_some(boost::asio::buffer(bufRec,max_len),
                                   boost::bind(&clientSession::handle_read,
