SRBEX_DATA_PNP structure (storport.h)

  • Artikel

The SRBEX_DATA_PNP structure contains the request data for an extended plug and play (PNP) SRB.

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.
