在某些时候我们的系统中会出现一些无法被正常删除的文件，如果想要强制删除则需要在驱动层面对其进行解锁后才可删掉，而所谓的解锁其实就是释放掉文件描述符（句柄表）占用，文件解锁的核心原理是通过调用ObSetHandleAttributes函数将特定句柄设置为可关闭状态，然后在调用ZwClose将其文件关闭，强制删除则是通过ObReferenceObjectByHandle在对象上提供相应的权限后直接调用ZwDeleteFile将其删除，虽此类代码较为普遍，但作为揭秘ARK工具来说也必须要将其分析并讲解一下。

首先封装lyshark.h通用头文件，并定义好我们所需要的结构体，以及特定未导出函数的声明，此处的定义部分是微软官方的规范，如果不懂结构具体含义可自行去微软官方查阅参考资料。
