NT File system driver

Hi there,
A question concerning NT file system driver :

As it is not totally clear to me from the IFS :

For Read or Write , synchronous or Non synchronous IO cases , what sould be
used as the offset (start point) for reading from the file :
FileObject->CurrentByteOffset.QuadPart or
irpSp->Parameters.Read(Write).ByteOffset.QuadPart (which one to use in
every case )

thanks,
Zvi

Hi Zvi,

You must use irpSp->Parameters.Read(Write).ByteOffset.QuadPart in both
cases.
