100分求问 error C2065: “SIO_RCVALL” : 未声明的标识符

[NiMaMaiPi2006]

是怎么回事
我包含了winsock2.h

[netsys2]

#define SIO_RCVALL _WSAIOW(IOC_VENDOR,1)

[netsys2]

#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)

我也使找了半天才知道那是微软新添的，

[RiNiMaDePi2006]

WSAIoctl(rawsock, SIO_RCVALL, &lpvBuffer, sizeof(lpvBuffer), NULL, 0, &lpcbBytesReturned, NULL, NULL);

我把鼠标拿到SIO_RCVALL下 提示的就是#define SIO_RCVALL _WSAIOW(IOC_VENDOR,1)

(我是.NET)

忘换号了..
楼主就是我

[alwaysakid]

#define _WIN32_WINNT 0x600

[RiNiMaDePi2006]

老A 我在头文件加了你那句 报错重复定义
warning C4005: “_WIN32_WINNT” : 宏重定义

我的头文件顺序
#include <afxwin.h>
#include <Winsock2.h>

[RiNiMaDePi2006]

WSAIoctl(rawsock, SIO_RCVALL, &lpvBuffer, sizeof(lpvBuffer), NULL, 0, &lpcbBytesReturned, NULL, NULL);
