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

/ WinSock DLL /
return;
}
/ Confirm that the WinSock DLL supports 22/
/ Note that if the DLL supports versions greater /
/ than 22 in addition to 22, it will still return /
/ 22 in wVersion since that is the version we /

if ( LOBYTE( wsaDatawVersion ) != 1 ||
