关于获取本地所有IP地址的办法

Lua获取本地IP地址如何通过Lua脚本获取本机的IP地址，需要用到socket.lua脚本。看官方帮助文档，觉得直接使用是没什么问题，直接使用”socket”服务也没问题，但系统一直提示缺少东西，很是让人烦，刚接触又不那么了解，真是棘手。关于获取IP地址的代码段如下：local socket = require("socket") print(os.time()) function GetAdd(hostname) 阅读详情

XP系统中，本地连接属性：ICP/IP属性：高级中，IP设置可以添加多个IP，我想问的是：

1、MFC中，如何得到这些IP？

2、在其他 Windows操作系统中，是否一样的处理？

谢谢

按照autoware.universe官方从零搭建自己的自动导航小车（三）（续）本文介绍了在Autoware框架下完善自定义传感器套件描述包的详细过程。主要内容包括：1）创建传感器描述包tinyplc_sensor_kit_description，包含YAML标定文件和URDF模型；2）配置传感器与车辆基座的相对位姿，实现sensor_kit.xacro和sensors.xacro宏文件；3）更新sensor_kit.launch.xml文件以集成激光雷达和GNSS/IMU驱动。通过xacro验证URDF模型正确性后，下一步计划接入Helios16激光雷达数据并在Rviz2中验证点云显阅读详情

GetAdaptersInfo()函数.



int _tmain(int argc, _TCHAR* argv[])

{

	PIP_ADAPTER_INFO pAdapterInfo = 0;

	ULONG uSize = 0;

	PIP_ADDR_STRING pAddress = 0;



	GetAdaptersInfo(pAdapterInfo, &uSize);

	pAdapterInfo = (PIP_ADAPTER_INFO)new BYTE[uSize];

	

	if (GetAdaptersInfo(pAdapterInfo, &uSize) == ERROR_SUCCESS)

	{

		while(pAdapterInfo)

		{

			printf_s("网卡名=%s\n", pAdapterInfo->Description);

			pAddress = &pAdapterInfo->IpAddressList;

			

			while(pAddress)

				pAddress = pAddress->Next;
