I am interested in getting any information about how to directly access
SCSI devices in C.  The only documentation I have been able to find
are the comments in the devices/scsidisk.h header file and some
(conflicting) information included with my GVP controller.  I would like
to find more complete information and a commented sample program that
actually does something (anything :-).

My particular problem is that I am trying to directly access my WT-150
tape drive directly (this is the GVP TapeStore product).  Using the
information I was able to glean from the header file, I was able to
get it to retension the tape, so some SCSI commands are getting through.

However, any data reads and writes return a GVP specific error (i think)
about not being able to find the device.  I am puzzled :-)


If somebody could give me any pointers, I would appreciate it.

Thanks
