这是服务器端代码,运行时提示
We are awaiting a connection on port 5150.
accept failed with error 10014
这是怎么回事??
源代码如下:

#include <winsock2.h>
#include <stdio.h>

void main(void)
{
WSADATA wsaData;
SOCKET ListeningSocket;
SOCKET NewConnection;
SOCKADDR_IN ServerAddr;
SOCKADDR_IN ClientAddr;
int ClientAddrLen;
int Port = 5150;
int Ret;
char DataBuffer[1024];

if ((Ret = WSAStartup(MAKEWORD(2,2), &wsaData)) != 0)
{
printf("WSAStartup failed with error %d\n", Ret);
return;
}


if ((ListeningSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP))
== INVALID_SOCKET)
{
printf("socket failed with error %d\n", WSAGetLastError());
WSACleanup();
return;
}


ServerAddr.sin_family = AF_INET;
ServerAddr.sin_port = htons(Port);
ServerAddr.sin_addr.S_un.S_addr = htonl(INADDR_ANY);



if (bind(ListeningSocket, (SOCKADDR *)&ServerAddr, sizeof(ServerAddr))
== SOCKET_ERROR)
{
printf("bind failed with error %d\n", WSAGetLastError());
closesocket(ListeningSocket);
WSACleanup();
return;
}


if (listen(ListeningSocket, 5) == SOCKET_ERROR)
{
printf("listen failed with error %d\n", WSAGetLastError());
closesocket(ListeningSocket);
WSACleanup();
return;
}

printf("We are awaiting a connection on port %d.\n", Port);



if ((NewConnection = accept(ListeningSocket, (SOCKADDR *) &ClientAddr,
&ClientAddrLen)) == INVALID_SOCKET)
{
printf("accept failed with error %d\n", WSAGetLastError());
closesocket(ListeningSocket);
WSACleanup();
return;
}


printf("We successfully got a connection from %s:%d.\n",
inet_ntoa(ClientAddr.sin_addr), ntohs(ClientAddr.sin_port));



closesocket(ListeningSocket);



printf("We are waiting to receive data...\n");

if ((Ret = recv(NewConnection, DataBuffer, sizeof(DataBuffer), 0))
== SOCKET_ERROR)
{
printf("recv failed with error %d\n", WSAGetLastError());
closesocket(NewConnection);
WSACleanup();
return;
}

printf("We successfully received %d byte(s).\n", Ret);



printf("We are now going to close the client connection.\n");

closesocket(NewConnection);


WSACleanup();

WSAEFAULT(10014) Bad address.
地址错误

[Phenix_Nirvana]

这是服务器端，怎么会错了？？代码里面并没有制定地址阿？

应该怎么解决呢？

[zhutao9_21]

系统检测到在一个调用中尝试使用指针参数时的无效指针地址。

[Jarrylogin]

你的IP地址没设定

[Jarrylogin]

//设定地址
serv.sin_addr.s_addr=inet_addr("211.65.60.18");
serv.sin_family=AF_INET;
serv.sin_port=htons(2406);
addlen=sizeof(serv);

[oyljerry]

如上设定地址就好了

[Phenix_Nirvana]

设定之后还是出现同样错误！！！！

[ChinaBJZ]

ServerAddr.sin_addr.S_un.S_addr = htonl(INADDR_ANY);
ServerAddr.sin_addr.S_un.S_addr = INADDR_ANY;

应该是这样的吧。

[lonenomad]

我试了一试，改了之后还是有错误，不过我这台机器上没有网卡，呵呵，不知是不是这个原因，我的是BIND错误。

[Phenix_Nirvana]

ip地址设定了，还是不行。

[wenxinfly]

那么给初学者提供几本书吧！！

[gdy119]

10014 服务器提供的IP地址错误！
象这样绝对没问题！
serv.sin_addr.s_addr = htonl(INADDR_ANY);
serv.sin_family=AF_INET;
serv.sin_port=htons(2406);

[HunterForPig]

初学者用这本书，要小心哦！

[celerityok]

mark!

[DentistryDoctor]

你有这本书的配套光盘？

[freeshoot]

照我的试试：

// 在accept前加上这句：
ClientAddrLen = sizeof(SOCKADDR);

if ((NewConnection = accept(ListeningSocket, (SOCKADDR *) &ClientAddr,
&ClientAddrLen)) == INVALID_SOCKET)

[friendzj]

楼上的，为什么说初学者用这本书要小心？？这本书问题很多？

[lovelyxiaoyu]

void main(void)
{
WSADATA wsaData;
SOCKET ListeningSocket;
SOCKET NewConnection;
SOCKADDR_IN ServerAddr;
SOCKADDR_IN ClientAddr;
int ClientAddrLen;
int Port = 5150;
int Ret;
char DataBuffer[1024];
ClientAddrLen = sizeof(SOCKADDR_IN);

~~烂书，不负责
