Module Name:
tape.h
Abstract:
These are the structures and defines that are used in the
SCSI tape class drivers. The tape class driver is separated
into two modules. An export driver called SCSITAPE.SYS which
provides a OS dependant wrapper for the OS independant and
a tape drive specific minitape driver. The interface between
these two drivers is also defined in this file.
