Ok, What do you mean... It seems to me your saying
that if I rename the
file and name a new one in it's place the running process (simh) will
continue to access the old file..(perhaps by inode)
yes. Unix = almost everything mapped to an inode.
Still true if I use links?
You can even delete the file... it will just modify the directory
entry (and internally decrement a reference counter probably from 2 to
1).
And what if simh closes and opens the file as needed?
That would work, but you need to notify simh one way or another. You
have to find a way to tell simh which device to close/reopen/reattach.
If it doesn't matter, eg. you ask simh to reattach all the devices, a
unix 'signal' can be used I guess.
Anyway I pretty sure your hack won't be supported by any OS running on
top of simh, I hope I'm wrong.
