求教WSAIoctl函数使用

Question

救教各位大虾，我在WIN98中使用WSAIoctl函数可以正常运行，但是同样的代码到了WIN2000下就报错，WINSOCK错误号是10038，这是为什么？是引用的链接库不对吗？

WSAIoctl
The Windows Sockets WSAIoctl function controls the mode of a socket.int WSAIoctl (
  SOCKET s,                                               
  DWORD dwIoControlCode,                                  
  LPVOID lpvInBuffer,                                     
  DWORD cbInBuffer,                                       
  LPVOID lpvOUTBuffer,                                    
  DWORD cbOUTBuffer,                                      
  LPDWORD lpcbBytesReturned,                              
  LPWSAOVERLAPPED lpOverlapped,                           
  LPWSAOVERLAPPED_COMPLETION_ROUTINE lpCompletionROUTINE  
);
 
Parameters
s 
[in] A descriptor identifying a socket. 
dwIoControlCode 
[in] The control code of operation to perform. 
lpvInBuffer 
[in] A pointer to the input buffer. 
cbInBuffer 
[in] A number indicating the size of the input buffer. 
lpvOutBuffer 
[out] A pointer to the output buffer. 
cbOutBuffer 
[in] A number indicating the size of the output buffer. 
lpcbBytesReturned 
[out] A pointer to actual number of bytes of output. 
lpOverlapped 
[in] A pointer to a WSAOVERLAPPED structure (ignored for non-overlapped sockets). 
lpCompletionRoutine 
[in] A pointer to the completion routine called when the operation has been completed (ignored for non-overlapped sockets). QuickInfo
  Windows NT: Yes
  Windows: Yes

2000也是nt,把报的错贴上sckNotSocket 10038 描述符不是套接字。
