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 <iostream>
#include <winsock2.h>
#include <ws2tcpip.h>
#include <iphlpapi.h>

#pragma comment(lib, "Ws2_32.lib")
#pragma comment(lib, "IPHLPAPI.lib")

int main() {
    // 初始化Winsock
    WSADATA wsaData;
    int result = WSAStartup(MAKEWORD(2, 2), &wsaData);
    if (result != 0) {
        std::cerr << "WSAStartup failed with error: " << result << std::endl;
        return 1;
    }

    // 获取网卡信息
    ULONG outBufLen = 0;
    result = GetAdaptersAddresses(AF_UNSPEC, GAA_FLAG_INCLUDE_PREFIX, nullptr, nullptr, &outBufLen);
    if (result != ERROR_BUFFER_OVERFLOW) {
        std::cerr << "GetAdaptersAddresses failed with error: " << result << std::endl;
        WSACleanup();
        return 1;
    }
    auto addresses = (IP_ADAPTER_ADDRESSES*)malloc(outBufLen);
    result = GetAdaptersAddresses(AF_UNSPEC, GAA_FLAG_INCLUDE_PREFIX, nullptr, addresses, &outBufLen);
    if (result != NO_ERROR) {
        std::cerr << "GetAdaptersAddresses failed with error: " << result << std::endl;
        free(addresses);
        WSACleanup();
        return 1;
    }

    // 禁用IPv6功能
    for (auto adapter = addresses; adapter != nullptr; adapter = adapter->Next) {
        for (auto address = adapter->FirstUnicastAddress; address != nullptr; address = address->Next) {
            if (address->Address.lpSockaddr->sa_family == AF_INET6) {
                auto sockaddr = reinterpret_cast<sockaddr_in6*>(address->Address.lpSockaddr);
                sockaddr->sin6_family = AF_UNSPEC;
                std::cout << "IPv6 disabled for adapter: " << adapter->FriendlyName << std::endl;
            }
        }
    }

    free(addresses);
    WSACleanup();
    return 0;
}

该代码使用了Windows Socket API和IP Helper API来获取网卡信息并禁用IPv6功能。具体来说，它使用GetAdaptersAddresses函数获取所有网卡的IP地址和相关信息，然后遍历每个网卡的IPv6地址并将其地址族设置为AF_UNSPEC，从而禁用IPv6功能。
