分享raw socket question
为什么下面语句编译通不过，是不是winsocket不支持？
怎么解决？谢谢
setsockopt(sockfd,IPPROTO_IP,IP_HDRINCL,&on,sizeof(on));

哦，解决了，原来IP_HDRINCL定义在文件Ws2tcpip.h中

(all platforms) Winsock 2
Raw I[CG]MP No Yes Yes Yes
IP_HDRINCL No No No Yes
Raw TCP/UDP No No No No

winsock programmer's FAQ
These stacks do not support raw IP or "packet capturing" from the Winsock layer.
Notice that raw TCP and UDP ar'nt possible directly under Winsock 2. Instead ,
you must use IP_HDRINCL and build your own IP and TCP or UDP headers.
Under Windows NT and Windows 2000,only userss that are members of the Administrator group can open raw sockets.

on = TRUE;
err = setsockopt(sockfd, IPPROTO_IP, IP_HDRINCL, (char*)&on, sizeof(on));
这个能用！你试一试！
