C++中的IPv6网络程序设计

while(ptr)
{
socklisten[i]=socket(ptr->ai_family,ptr->ai_socktype,ptr->ai_protocol　);
if(socklisten[i]==INVALID_SOCKET){//创建失败处理；}
rc=bind(socklisten[i],ptr->ai_addr,ptr->ai_addrlen);
if(rc==SOCKET_ERROR){//绑定失败处理}
rc=listen(slisten[i],7)//开始监听
if(rc==SOCKET_ERROR){//监听失败处理}
i++;
ptr=ptr->ai_next;
}
　　　　　。。。
//完成其他编程
