Native Wifi 简介

    是提供给软件开发者来开发windows 无线管理的一系列API。编程人员可以通过这些函数来进行相关的无线管理，当然我们还可以通过netsh终端命令来管理，这对于非编程人员就可以简单的实现，具体可以查阅相关资料去了解。

    API如下：

• WLAN_NOTIFICATION_CALLBACK
• WlanAllocateMemory
• WlanCloseHandle
• WlanConnect
• WlanDeleteProfile
• WlanDisconnect
• WlanEnumInterfaces

无线的连接相关知识

 

从windows的无线网络属性设置窗口来对比，在API编程中，同样有个配置文件来设置这些属性的，那就是profile文件，通过编写xml文件来设置相关属性。
