Hi Everyone,
I am currently trying to list the directory entries using NtQueryDirectoryFile() but I found out that there is another similar call NtQUeryDirectoryObject() to NtQueryDirectoryFile().
I tried to look at the internet to find the difference between these two calls but I have not found much except for that fact that I would have to call NtOpenDirectoryObject before I use NtQueryDirectoryObject and NtQueryDirectoryObject reads information from a namespace directory. Here is an example.

Can anyone give me why there are such two functions? I know that this sounds very silly but I will really appreciate if anyone can give me some insight.
Thank you very much in advance.

Windows has an object store, that includes many things, including devices,
volumes, and various other objects. These are not file system things, so
they make no sense to be file directories. So instead, they are kept in
the object store. See
http://www.microsoft.com/technet/sysinternals/SystemInformation/WinObj.mspx
for a tool that will allow you to explore it.

NtQueryDirectoryObject reads information from a namespace directory, and
NtQueryDirectoryFile reads information from an on-disk filesystem directory.
