分享问关于WSAStartup(WINSOCK_VERSION,&wsaData）的参数
用WSAStartup(/*WINSOCK_VERSION*/WINSOCK_VERSION,&wsaData)提示错误：
error C2065: 'WINSOCK_VERSION' : undeclared identifier
可能是少一个包含文件，我想
该怎么对付

如果是 Winsock 1.1 则
#define WINSOCK_VERSION MAKEWORD(2,0)
改为
#define WINSOCK_VERSION MAKEWORD(1,1)
#define WINSOCK_VERSION MAKEWORD(2,0)
改为
#define WINSOCK_VERSION MAKEWORD(1,1)

//winsock 2.0
#define WINSOCK_VERSION MAKEWORD(2,0)
if(WSAStartup(WINSOCK_VERSION,&wsadata))
{
MessageBox(NULL,"Your system does not support WinSocket2!","Error!",MB_OK);
return -1;
}
if(wsadata.wVersion!=WINSOCK_VERSION)
{
MessageBox(NULL,"Your system does not support WinSocket2!","Error!",MB_OK);
WSACleanup();
return -2;
}
