win驱动开发笔记-驱动加载

手动加载

代码加载(win32)

 /*安装驱动程序流程：
   1、调用OpenSCManager()打开服务控制管理器
  
   2、调用CreateService()创建一个服务，服务类型为内核驱动
  
   3、调用OpenService()取得服务句柄
   启动服务
  
  4、调用StartService()启动服务
   停止服务
  
  4、调用ControlService()停止服务
   删除服务
  
  4、调用DeleteService()删除服务
  
  5、调用CloseServiceHandle()关闭服务句柄

操作驱动程序流程：  
   1、调用CreateFile()取得设备句柄
  
   2、调用DeviceIoControl()传递I/O控制代码
  
   3、调用CloseHandle()关闭设备句柄
