ipv6 address 的设定

原文地址： http://blog.csdn.net/xiaoweibeibei/article/details/6070936

记得看过一篇日志说ioctl无法实现ipv6地址的设定，今天没事研究了下，其实并非那位仁兄所说，算了，多的不说了，上代码(代码在ubuntu10.04上调试通过)，当然这是个例子程序，欢迎大家拍砖来完善！

{
 IPV6_REQ ifreq6;
 ifreq6.ifr6_prefixlen = 64;
 inet_pton(AF_INET6, "2002:12::223:45", &ifreq6.ifr6_addr);
 set_ipv6("eth1",ifreq6);
 printf("set ipv6 success!");          
}
int set_ipv6(char *name,IPV6_REQ ifreq6)
{
    
 int sockfd6;
 struct ifreq ifr;
 if((sockfd6 = socket(AF_INET6, SOCK_DGRAM, 0)) < 0)
{
perror("Socket");
return -1;
}
strcpy(ifr.ifr_name, name); 
ioctl(sockfd6, SIOCGIFINDEX, &ifr); 
ifreq6.ifr6_ifindex = ifr.ifr_ifindex;
if(ioctl(sockfd6,SIOCSIFADDR, &ifreq6)< 0)
{
printf("error in get_ipaddr11/n");
perror("ioctl");
return -1;
}
return 0;
}
