大家好 我在示例应用程序中编写了代码.

Hi all i wrote a code in sample application.

char szHostName[255]; int iEc = -1; addrinfo* pAdInfo = NULL; // get the local hostname if( gethostname(szHostName, 255) == SOCKET_ERROR ) { return ; } CString sTmp(szHostName); ::AfxMessageBox(sTmp); iEc = getaddrinfo(szHostName, NULL, NULL, &pAdInfo); if( S_OK == iEc ) { sTmp.Format(_T("family[%d]"),pAdInfo->ai_family); ::AfxMessageBox(sTmp); }

它在窗口7中提供了不同的家庭，在窗口XP中提供了不同的家庭 胜利7:AF_INET6 赢得XP; AF_INET 我的问题是我怎样才能在两者中获得相同的ip4. Thankyou

推荐答案

传递addrinfo结构以指定类型(IPv4或IPv6).请参见 getaddrinfo() [ ^ ]函数和 addrinfo [ ^ ]结构.当不传递任何addrinfo 结构或将ai_family成员设置为AF_UNSPEC时，返回的族类型在安装时(始终在Vista和更高版本中)为IPv6. Pass an addrinfo structure to specify the type (IPv4 or IPv6). See the getaddrinfo()[^] function and the addrinfo[^] structure. When passing no addrinfo structure or setting the ai_family member to AF_UNSPEC, the returned family type is IPv6 when it is installed (always with Vista and later).
