An acquaintannce of mine from Toronto (who I can't readily get in touch with
now) told me about two calls, AddDosNode and DeleteDosNode (or it may be
DOS; this was verbal) that do All The Right Things in hitting the di_DevInfo
list to add volumes, devices, etc.

He mentioned they were documennted in some obscure CATS publication, an
"AmigaDos Technical Reference" (or something similar-sounding), that was
not, repeat *not* the one in the back of the 1.0 RKM's, published by Bantam
in the AmigaDos manual, etc.  Something *entirely* different, just having a
similar-sounding name.

Now, nobody I've talked to has heard of anything of the sort.  Has anyone
out there heard of such a thing?  I'm starting to have serious doubts
about its existence.

The problem I'm really trying to manage is to signal open "Please insert
volume..." requesters, so the user doesn't have to click "retry."  I believe
most else can be handled by hitting the list directly, using Forbid() and
Permit().
 
Does anyone know how to solve this problem?  I could, I suppose, keep
a MsgPort open for each volume I know about and put up the requesters
myself, but this is somewhat expensive in terms of memory, and some
experiments by others in using something other than a process' pr_MsgPort
for the packet port have uncovered difficulties.  It seems much simpler
to use existing Dos features.  And no matter what I do, I can't otherwise
handle the requester for a volume that has never been mounted.

Thanks for any assistance, and remember that this semi-mythical "Technical
Reference" is *not* the obvious one.
