socket还不是太熟悉，首先要链接库文件
下面是简单的测试代码，可以运行，已经测试过^^.

#include#include #pragma comment(lib,"ws2_32.lib")int main(){ SOCKET serversock,clientsock; WSADATA wsa; char buf[100]; struct sockaddr_in serveraddr; WSAStartup(MAKEWORD(2,2),&wsa); serversock=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP); //使用TCP协议 serveraddr.sin_family=AF_INET; serveraddr.sin_port=htons(6666); serveraddr.sin_addr.S_un.S_addr=INADDR_ANY; //自动获取本地IP地址 bind(serversock,(struct sockaddr*)&serveraddr,sizeof(serveraddr)); listen(serversock,1); clientsock=accept(serversock,NULL,NULL); //返回新的socket memset(buf,0,100); recv(clientsock,buf,100,0); //接收客户端的信息 strcat(buf," this is server"); send(clientsock,buf,100,0); //服务器发送信息 closesocket(serversock); WSACleanup(); //释放资源 return 0;}
