Figure: The <#1434#> Scsi_Pointer<#1434#> Structure
The variables in this structure can be used in <#1438#> any<#1438#> way necessary in
the low-level driver. Typically, 161 points to the current entry
in the 162, 163 counts the number of
entries remaining in the 164, 165 is used as a
pointer into the buffer, and 166 counts the characters
remaining in the transfer. Some host adapters require support of this
detail of interaction---others can completely ignore this structure.
The second set of variables provide convenient locations to store SCSI
status information and various pointers and flags.
