SRBEX_DATA_BIDIRECTIONAL structure (storport.h)

The SRBEX_DATA_BIDIRECTIONAL structure contains the extended SRB data for bi-directional transfer commands.

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.

 

Syntax
