基本WinSock编程问题

[xuxinjun]

在《Windows网络编程》第一章TCP/IP服务器程序中，有如下代码：

#include <winsock2.h>

void main(void)
{
WSADATA wsaData;
SOCKET ListeningSocket,NewConnection;
SOCKADDR_IN ServerAddr,ClientAddr;
int Port=5150;

WSAStartup(MAKEWORD(2,2),&wsaData);

ListeningSocket=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);

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

bind(ListeningSocket,(SOCKADDR*)&ServerAddr,sizeof(ServerAddr));

listen(ListeningSocket,5);

int ClientAddrLen;
NewConnection=accept(ListeningSocket,(SOCKADDR*)&ClientAddr,&ClientAddrLen);

closesocket(NewConnection);
closesocket(ListeningSocket);

WSACleanup();

}
按说如无客户机连接请求时，程序运行到accept()时应该被阻塞，然而我在调试时，程序却并不阻塞，而是直接往下运行，并在运行到main()函数尾部时弹出对话框提示“please enter the path for CRTO.C”，请问这是怎么回事？

你在每个可能出错的地方都加上错误处理试试看，看错在哪里了，比如bind

nRet=bind(ListeningSocket,(LPSOCKADDR)&ServerAddr,sizeof(ServerAddr));
if(nRet==SOCKET_ERROR)
{
AfxMessageBox("Bind Socket Fail!");
closesocket(ListeningSocket);
return ;
}
