Hi All,
Can anyone tell me what is the DataBuffer field will represent. I want to
know which is the field, that will have the Sense Code and Additional Sense
code information?

Hi Ramesh,
For SCSI_REQUEST_BLOCKs of type SRB_FUNCTION_EXECUTE_SCSI, you can
typically find the sense data (which contains the below error info) in
the PVOID SenseInfoBuffer field. Note that this is a variable-length
field (see SenseInfoBufferLength field), and may be NULL, etc. As long
as you carefully check your access to fields(*), you can always use the
publicly defined _SENSE_DATA structure found in SCSI.H.
The DataBuffer field for EXECUTE_SCSI requests represents the data which
is transferred either to or from the device as part of the command, so
you probably don’t want to work with that field.
I realize MSDN doesn’t do a great job defining all the bits and pieces
in this area, but I think you’ll find it has significantly improved over
the past couple years (and we’ll still working on making it better).
Hth,
.
(*) To ensure the buffer is large enough. Easy way is to allocate a
SENSE_DATA structure on the stack (18 bytes), zero it, then copy the
buffer to it for review. Modifications copied back the same way. More
complex ways typically use the RTL_SIZEOF_THROUGH_FIELD() macro.
