FsContext field of the FileObject

NTDEV

Hi all,

How can a user application calling CreatFile(), pass an open structure to
driver as a part of the FsContext field of the FileObject, created by the
IO Manager as a result of this call?

Thanks a lot,
Rajinder

The user can’t pass anything as part of the FsContext field. This field is
reserved for the use of Top Level drivers, typically FileSystem drivers.
Generally such a driver will record information about the specific user
create request that started this IO connection to the top level device
driver. A filesystem driver, for example, might store information about
which file was opened by a NtCreateFile request.
