setsockopt的IP_HDRINCL选项未定义怎么解决？？

[sboom]

我原来以为是 mstcpip.h 里面定义，后来人家给了一个，还是没定义。

人家给我的那个的内容是
// Copyright (c) Microsoft Corporation. All rights reserved.
#if _MSC_VER > 1000
#pragma once
#endif

/* Argument structure for SIO_KEEPALIVE_VALS */

struct tcp_keepalive {
u_long onoff;
u_long keepalivetime;
u_long keepaliveinterval;
};

// New WSAIoctl Options

#define SIO_RCVALL _WSAIOW(IOC_VENDOR,1)
#define SIO_RCVALL_MCAST _WSAIOW(IOC_VENDOR,2)
#define SIO_RCVALL_IGMPMCAST _WSAIOW(IOC_VENDOR,3)
#define SIO_KEEPALIVE_VALS _WSAIOW(IOC_VENDOR,4)
#define SIO_ABSORB_RTRALERT _WSAIOW(IOC_VENDOR,5)
#define SIO_UCAST_IF _WSAIOW(IOC_VENDOR,6)
#define SIO_LIMIT_BROADCASTS _WSAIOW(IOC_VENDOR,7)
#define SIO_INDEX_BIND _WSAIOW(IOC_VENDOR,8)
#define SIO_INDEX_MCASTIF _WSAIOW(IOC_VENDOR,9)
#define SIO_INDEX_ADD_MCAST _WSAIOW(IOC_VENDOR,10)
#define SIO_INDEX_DEL_MCAST _WSAIOW(IOC_VENDOR,11)

// Values for use with SIO_RCVALL* options
#define RCVALL_OFF 0
#define RCVALL_ON 1
#define RCVALL_SOCKETLEVELONLY 2

难道这个头文件是不对的还是在其他什么地方定义？
