简单的flash策略文件服务器！

最近在做一个flash小游戏，
众所周知，flash连接服务器socket的时候，需要向服务器请求策略文件。
以下是一个简单的策略文件服务器的代码c++:

 #include <Winsock2.h>
 #include <stdio.h>
 #pragma comment(lib,"WS2_32.lib")
 #define _CRT_SECURE_NO_WARNINGS
 void main()
 {
     WSADATA wsd;
     SOCKET server;                                            //服务器socket
     SOCKADDR_IN addrSrv;
     SOCKADDR_IN addrClient;
     SOCKET client;                                            //连接的客户端socket
     char szPolicy[] = "";
     strcat_s(szPolicy, , "<?xml version='1.0'?>");
     strcat_s(szPolicy, , "<cross-domain-policy>");
     strcat_s(szPolicy, , "<site-control permitted-cross-domain-policies='all'/>");
     strcat_s(szPolicy, , "<allow-access-from domain='*' to-ports='*'/>");
     strcat_s(szPolicy, , "</cross-domain-policy>");
     int len;
     if (WSAStartup(MAKEWORD(, ), &wsd) != )
     {
         printf("start up failed!\n");
         return;
     }
     server = socket(AF_INET, SOCK_STREAM, );                    //创建socket
     addrSrv.sin_addr.S_un.S_addr = htonl(INADDR_ANY);            //设置地址
     addrSrv.sin_family = AF_INET;
     addrSrv.sin_port = htons();                            //设置端口号
     bind(server, (SOCKADDR*)&addrSrv, sizeof(SOCKADDR));        //绑定
     printf("flash策略文件服务器已启动！\n");    

     listen(server, );                                        //设置最多连接数
     int count = ;
     len = sizeof(SOCKADDR);
     while ()
     {
         client = accept(server, (SOCKADDR*)&addrClient, &len);    //接收客户端连接
         char buff[] = "";
         recv(client, buff, , );
         szPolicy[strlen(szPolicy)] = '\0';
         send(client, szPolicy, strlen(szPolicy), );
         closesocket(client);
         count++;
         printf("已成功返回%d个客户端！", count);
     }
     WSACleanup();
 }
