函数NtQueryObject可以得到一些内核对象信息，但是远远不够， 我想要知道都有谁打开了这个内核对象，《深入解析Windows操作系统》里面说，一个内核对象存在一个“已打开句柄的列表”，该列表记录了所有打开内核对象的对象的相关信息，可是如何得到他呢？ |

NtQueryObject 的第三个参数应该返回了足够的信息吧。
而且在调用前枚举进程ID进行调用，那么自然就知道谁打开的(楼主需要的是这个吗？) 楼下贴代码。 |

_SYSTEM_INFORMATION_CLASS有这么多枚举么？
我看到的资料只有5个 我想的和你说的似乎不太一样 比如说当前进程的内核对象的使用计数为3，我想知道哪3个进程拥有当前进程的句柄。不用枚举所有进程，书上说内核对象头中记载了这一信息 |
|
|
你说的是得到当前进程句柄表中所有句柄的信息，我只想要当前进程对应的内核对象的信息
|
|
|
有没有人知道啊

有人知道吗

我也想知道
