The low 24 bits are the options. Look in NTIFS.H for FILE_DIRECTORY_FILE -
those are the 24 bits. Note that these are bit definitions.
The upper 8 bits are the disposition. Look for FILE_OPEN in ntifs.h, as
this describes the values of the upper 8 bits. Note that these are discreet
values.

Subject: [ntfsd] Re: Anatomy Of Options value in IRP_MAJOR_CREATE’s
IO_STACK_LOCATION
Thanks for your reponse Dave. the information I was looking for is… how
is the Options parameter value laid out.
<<<io_stack_location->Parameters->Create.Options>>>>
What is the strcuture of this parameter for file create operation? If I
have to do bit wise access, how does it look like?
Please forgive my little knowledge in this. I am just starting out on FSD.
Thanks.
Naveen
