服务端：
程序代码：

WSADATA wsaData;
int err;

wVersionRequested = MAKEWORD(1,1);

err = WSAStartup(wVersionRequested, &wsaData);
if(err != 0) return;
if(LOBYTE(wsaData.wVersion) != 1 || HIBYTE(wsaData.wVersion) != 1)
{
WSACleanup( );
return;
}

SOCKET sockSrv = socket(AF_INET,SOCK_STREAM,0);
SOCKADDR_IN addrSrv;
addrSrv.sin_addr.S_un.S_addr = htonl(INADDR_ANY);
addrSrv.sin_family = AF_INET;
addrSrv.sin_port = htons(6000);

bind(sockSrv,(SOCKADDR*)&addrSrv,sizeof(SOCKADDR));
listen(sockSrv,5);

SOCKADDR_IN addrClient;
int len = sizeof(SOCKADDR);

while(1)
{
char sendBuf[500];
char recvBuf[500];
SOCKET sockConn = accept(sockSrv,(SOCKADDR*)&addrClient,&len);

sprintf(sendBuf,"Welcome %s to XXX",inet_ntoa(addrClient.sin_addr));

recv(sockConn,recvBuf,100,0);
printf("%s",recvBuf);
closesocket(sockConn);
}

包含

我这里都可以运行哦  你的错误代码是什么？
#5
shafeilong2010-10-31 21:18
呵呵 #include <winsock2.h>
这里错了   应该是Win   要大写
LINK 那边要包含ws2_32.lib

//要连接上ws2_32.lib
#include<Winsock2.h>
#include<stdio.h>
void main()
{
    WORD wVersionRequested;
    WSADATA wsaData;
    int err;

    err = WSAStartup( wVersionRequested, &wsaData );
    if ( err != 0 ) {
        
        return;
    }
    if ( LOBYTE( wsaData.wVersion ) != 1 ||
        HIBYTE( wsaData.wVersion ) != 1 ) {

        closesocket(sockConn);
    }
}



#include<Winsock2.h>
#include<stdio.h>

    send(sockClient,"This is zhangsan",strlen("This is zhangsan")+1,0);
    closesocket(sockClient);
    WSACleanup();

}


这样就可以了

首先将服务器地址改为127.0.0.1 （默认的本机地址）
其次将每个函数的返回值检查下，判断调用是否成功 SOCKET_ERROR
再者 cmd中 用netstat -na 查看6000这个端口号是否被占用 如被占用换个
最后貌似有的平台或者硬件影响会导致链接很慢 ，如没有出现错误码提示，那么耐心等个几分钟看看！
