ScsiPortGetSrb function (srb.h)

The ScsiPortGetSrb routine returns a pointer to an active SCSI request for a particular logical unit.

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.
