Netware read file with offset!

NTFSD
1

Hi,
I would like to read a file in the Netware drive using ZwReadFile with the
specified offset, but it always returned me an error 0xC000000D (Invalid
Parameter). Below is my ZwCreateFile and ZwReadFile parameters:

LARGE_INTEGER Offset;
ULONG BufferSize = 256;

status = ZwCreateFile(&FileHandle, GENERIC_READ | SYNCHRONIZE, &oa,
&IoStatusBlock,
NULL, FILE_ATTRIBUTE_ARCHIVE,
FILE_SHARE_READ, FILE_OPEN,
FILE_NON_DIRECTORY_FILE |
FILE_SYNCHRONOUS_IO_NOALERT,
NULL, 0);

Offset.LowPart = 0;
status = ZwReadFile(FileHandle, NULL, NULL, NULL, &IoStatusBlock,
pBuffer, BufferSize, &Offset, NULL);

======================================================================
If I don’t specify the Offset in the ZwReadFile, it does a sequential
read and works fine. Thanks for any information to this problem.

Regards,
Sin-Lam

I don’t see the HighPart being set in the offset.
