The documentation on ZwQueryFileInformation is more or less clear and complete in the IFS kit. If you just want the name of the object see the IFS kit documentation for ObQueryNameString.

Subject: [ntfsd] about IoQueryFileInformation()
I found this founction in ntifs.h
NTKERNELAPI
NTSTATUS
IoQueryFileInformation(
IN PFILE_OBJECT FileObject,
IN FILE_INFORMATION_CLASS FileInformationClass,
IN ULONG Length,
OUT PVOID FileInformation,
OUT PULONG ReturnedLength
);
and I used it like this:
Filename = ExAllocatePool(NonPagedPool, length);
ULONG length = sizeof (FILE_NAME_INFORMATION) + (sizeof (WCHAR)*(MAXIMUM_FILENAME_LENGTH -1));
ntStatus = IoQueryFileInformation(FileObject, FileNameInformation,length,nameInformation,&length);
but the IoQueryFileInformation() returned STATUS_INVALID_PARAMETER.
please give me a hint.
