ScsiPortReadPortBufferUlong function (srb.h)

  • Artikel

The ScsiPortReadPortBufferUlong routine transfers a given 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.
