windows 禁用所有网卡的ipv6功能的c++代码

以下是禁用所有网卡的 IPv6 功能的 C++ 代码：

#include <Windows.h>
#include <netioapi.h>

#pragma comment(lib, "IPHLPAPI.lib")

int main()
{
    DWORD dwRet = 0;
    ULONG ulAf = AF_INET6;
    NET_IF_COMPARTMENT_ID ulCompartmentId = NET_IF_COMPARTMENT_ID_UNSPECIFIED;
    PIP_ADAPTER_ADDRESSES pCurrAddresses = NULL;
    PIP_ADAPTER_UNICAST_ADDRESS pUnicast = NULL;
    PIP_ADAPTER_ANYCAST_ADDRESS pAnycast = NULL;
    PIP_ADAPTER_MULTICAST_ADDRESS pMulticast = NULL;
    PIP_ADAPTER_DNS_SERVER_ADDRESS pDnServer = NULL;
    PIP_ADAPTER_PREFIX pPrefix = NULL;

    // 获取适配器信息
    dwRet = GetAdaptersAddresses(ulAf, GAA_FLAG_INCLUDE_ALL_INTERFACES | GAA_FLAG_SKIP_ANYCAST | GAA_FLAG_SKIP_MULTICAST | GAA_FLAG_SKIP_DNS_SERVER, NULL, NULL, &pCurrAddresses);
    if (dwRet != NO_ERROR)
    {
        return 1;
    }

    // 遍历适配器信息，禁用 IPv6
    for (PIP_ADAPTER_ADDRESSES pIf = pCurrAddresses; pIf != NULL; pIf = pIf->Next)
    {
        dwRet = SetIfEntryIpv6Enable(&pIf->IfIndex, FALSE);
        if (dwRet != NO_ERROR)
        {
            continue;
        }
    }

    // 释放适配器信息
    if (pCurrAddresses != NULL)
    {
        FreeAdaptersAddresses(pCurrAddresses);
        pCurrAddresses = NULL;
    }

    return 0;
}

这段代码使用了 Windows API 函数 `GetAdaptersAddresses` 和 `SetIfEntryIpv6Enable`，可以遍历所有网卡并禁用 IPv6 功能。注意需要链接 `IPHLPAPI.lib` 库。
