linux与windows通信

[shuaiying]

在linux上用C编写循环服务器,在windows中用MFC建立客户端,相互间不能连接,客户端报告连接错误.在Linux下两者能通信,同样在windows下两者也能通信,为什么?

代码发上来

可能是字节对齐的问题，导致数据不一致

[captain_x]

windows下不用cstring，直接用char试试

[ckc]

2楼说的有一定道理，有可能是编译器在细节上不一致

windows下主要代码:
void CLCDlg::OnConnectServer()
{
// TODO: Add your control notification handler code here
createSock();
if(connect(sock,(struct sockaddr*)&serverAddr,sizeof(serverAddr)))
{
AfxMessageBox("connect error");
return ;
}
}

void CLCDlg::OnSend()
{
// TODO: Add your control notification handler code here
CString str="hello";
int len;
len=send(sock,str,sizeof(str),0);

}

DWORD CLCDlg::startScok()
{
serverAddr.sin_family=AF_INET;
serverAddr.sin_addr.s_addr=inet_addr("159.226.75.221");
serverAddr.sin_port=htons(5790);
return 1;
}

DWORD CLCDlg::createSock()
{
sock=socket(AF_INET,SOCK_STREAM,0);
if(sock==INVALID_SOCKET)
{
AfxMessageBox("Wrong");
return -1;
}
return 1;
}

void CLCDlg::OnClose()
{
closesocket(sock) ;
}
