windows 使用c++代码禁用所有网卡的ipv6功能的完整代码

以下是一个禁用Windows所有网卡IPv6功能的C++代码示例：

#include <iostream>
#include <windows.h>
#include <iphlpapi.h>
#pragma comment(lib, "IPHLPAPI.lib")

int main() {
    // 获取网络适配器信息
    DWORD dwSize = 0;
    GetAdaptersAddresses(AF_UNSPEC, GAA_FLAG_INCLUDE_ALL_INTERFACES, NULL, NULL, &dwSize);
    PIP_ADAPTER_ADDRESSES pAddresses = (PIP_ADAPTER_ADDRESSES) malloc(dwSize);
    GetAdaptersAddresses(AF_UNSPEC, GAA_FLAG_INCLUDE_ALL_INTERFACES, NULL, pAddresses, &dwSize);

    // 遍历并禁用IPv6
    for (PIP_ADAPTER_ADDRESSES pCurrAddresses = pAddresses; pCurrAddresses != NULL; pCurrAddresses = pCurrAddresses->Next) {
        if (pCurrAddresses->OperStatus == IfOperStatusUp) {
            for (PIP_ADAPTER_UNICAST_ADDRESS pUnicast = pCurrAddresses->FirstUnicastAddress; pUnicast != NULL; pUnicast = pUnicast->Next) {
                if (pUnicast->Address.lpSockaddr->sa_family == AF_INET6) {
                    PIP_ADAPTER_INFO pAdapterInfo = NULL;
                    DWORD dwBufLen = 0;
                    GetAdaptersInfo(pAdapterInfo, &dwBufLen);
                    pAdapterInfo = (PIP_ADAPTER_INFO) malloc(dwBufLen);
                    GetAdaptersInfo(pAdapterInfo, &dwBufLen);

                    for (PIP_ADAPTER_INFO pAdapter = pAdapterInfo; pAdapter != NULL; pAdapter = pAdapter->Next) {
                        if (wcscmp(pAdapter->Description, pCurrAddresses->Description) == 0) {
                            DWORD dwOutBufLen = 0;
                            DWORD dwRetVal = 0;
                            MIB_IPINTERFACE_ROW row;
                            memset(&row, 0, sizeof(row));
                            row.Family = AF_INET6;
                            row.InterfaceLuid = pAdapter->Luid;
                            dwRetVal = GetIpInterfaceEntry(&row);
                            if (dwRetVal == NO_ERROR) {
                                row.UseAutomaticMetric = TRUE;
                                dwRetVal = SetIpInterfaceEntry(&row);
                                if (dwRetVal == NO_ERROR) {
                                    std::cout << "IPv6 has been disabled on interface " << pAdapter->Description << std::endl;
                                } else {
                                    std::cout << "SetIpInterfaceEntry() failed with error: " << dwRetVal << std::endl;
                                }
                            } else {
                                std::cout << "GetIpInterfaceEntry() failed with error: " << dwRetVal << std::endl;
                            }
                            break;
                        }
                    }
                    free(pAdapterInfo);
                }
            }
        }
    }

    free(pAddresses);
    return 0;
}

该代码使用了Windows API函数来获取网络适配器信息，并遍历每个适配器的每个IPv6地址，然后使用另一个Windows API函数来禁用IPv6。注意，此代码需要管理员权限才能正常运行。
