ipv6赋地址值的语句怎么写

PARAMREQUEST* pParam=(PARAMREQUEST*)lpParam;
CWnd* pWnd=(CWnd*)pParam->ptr;
SOCKET sock=socket(PF_INET6,SOCK_STREAM,0); //SOCKET sock=socket(AF_INET,SOCK_STREAM,0); //生成一个TCP的socket
SOCKADDR_IN6 sin;//结构体
sin.sin6_addr.s6_addr=inet_addr(pParam->sIP);
sin.sin6_family=PF_INET6; //sin.sin_family=AF_INET;
sin.sin6_port=htons(pParam->iPort);
sin.sin6_addr.s6_addr=inet_addr(pParam->sIP);总是出错
