ScsiPortReadRegisterBufferUlong macro (storport.h)
The ScsiPortReadRegisterBufferUlong routine transfers a specified number of ULONG values from the HBA to a buffer.
Note The SCSI port driver and SCSI miniport driver models may be altered or unavailable in the future. Instead, we recommend using the Storport driver and Storport miniport driver models.
