98与2000兼容问题

[qq_13939330]

我在xp,和2000下都能正常运行的程序，在98下却收不到包！
2000/xp send-->98正常，而 98send-->xp,2000失败！虽然send()函数调用成功，返回发送字节数，而
2000，xp却收不到包，可能由什么原因引起的？？

用sniffer抓包看看从网卡上发出了什么数据？另一端也sniffer看看有没有收到数据

楼主是不是用raw socket了？

[qq_13939330]

int CNetSocket::RecvDataEvent(SOCKET hSocket, char * pszBuffer, int nBufferSize, DWORD dwTimeout)
{
WSANETWORKEVENTS NetEvent;
HANDLE hReadEvent;
DWORD dwWaitResult ;
DWORD nRecvBytes = 0;

hReadEvent = CreateEvent(NULL, FALSE, FALSE, NULL);
if (hReadEvent == NULL)
{
return -1;
}

while( true )
{
if( WSAEventSelect(hSocket, (WSAEVENT) hReadEvent, FD_READ | FD_CLOSE)== SOCKET_ERROR )
{
CloseHandle(hReadEvent);
return -1;
}

dwWaitResult = WSAWaitForMultipleEvents(1, &hReadEvent, TRUE, dwTimeout, TRUE);
if (dwWaitResult != WSA_WAIT_EVENT_0)
{
break;
}

if(WSAEnumNetworkEvents(hSocket,(WSAEVENT)hReadEvent,&NetEvent) == SOCKET_ERROR)
{
break;
}

if( NetEvent.lNetworkEvents == FD_CLOSE)
{
return -2;
}

if( NetEvent.lNetworkEvents == FD_READ)
{
WSAEventSelect(hSocket, (WSAEVENT) hReadEvent, 0);
return RecvDataBlock(hSocket, pszBuffer, nBufferSize);
}
}

WSAEventSelect(hSocket, (WSAEVENT) hReadEvent, 0);
CloseHandle(hReadEvent);
return -1;
}


应该是这个函数的问题！
这函数在98下支持吗？

WSAEventSelect好像98不支持

[qq_13939330]

WSAEventSelect 98下绝对支持!
