I know, I know we all don't like those guys who talk to themselves
on mailing lists replying to their own emails, but since there were
no takers here's what I cooked up so far:
echo stop > /proc/n/ctl &
echo ping > /proc/n/note
cat /proc/n/note > /dev/null
That of course doesn't quite work either since once I resume 'n'
by issuing
echo start > /proc/n/ctl
the process fails with:
error reading <stdin>: interrupted
So the question remains -- what is the proper way of putting a process
that waits for an IO into a Stopped state?
Sorry that I keep bothering the list, but I can't really think
of anything here :-(
Thanks,
Roman.
