The closest appropriate function would be GetFileType, however it operates with integer file type codes, and has too few codes to distiguish types. Additionally, since I'd like to dump type name into a native description string, I have taken NtQueryObject.

Therefore if it returns an error for a socket, you can immediately fall back to the `Handle %p`. Or does the NtQueryObject actually provide any info about the socket that you read?

I thought it'd be useful to have a name of a handle type while creating a native description string. That's why I used NtQueryObject. However it's just an info string, so I agree that using NtQueryObject is not necessary here.
I will replace it with GetFileType.
