Ok, I'm a few steps closer to adding barcode support to a modified chg-zd-mtx
script. I have a two questions for some people in the know.
chg-scsi has the following params:
./chg-scsi -slot <param>
./chg-scsi -info
./chg-scsi -reset
./chg-scsi -eject
./chg-scsi -clean
./chg-scsi -label <param>
./chg-scsi -search <param>
./chg-scsi -status <param>
./chg-scsi -trace <param>
I know the first 4, as they are documented in the TAPE.CHANGERS file. I've
mostly figured out what -label <param> does, but to be sure I'm pretending to
not.
My question is, what do the last 5 items do? By that I mean, what do they
pass to the changer script, and what do they expect as return values. For
instance, I "believe" that -label's <param> is the amlabel of the current tape.
The changer script puts that, and the barcode, into a file, then returns
"0 0 0" if it worked. If it fails, it returns the slot, and the tape device.
Also, what is the format that amtape needs the barcode file to be in? Just for
testing I have it as:
<amlabel1> <barcode1>
<amlabel2> <barcode2>
<amlabel3> <barcode3>
...
Thanks...
