<P>Hi Nick,
|
|
<BR>
|
|
<P>so you say that:
|
|
<BR>
|
|
- frontend/sane-net crash
|
|
<BR>
|
|
- system shutdown of frontend machine
|
|
<BR>
|
|
<P>is handled by the tcp stack for unix, win32, os/2?
|
|
<BR>
|
|
<P>Then I would suggest we set the time to e.g. 24 hours
|
|
<BR>
|
|
(this makes sure that saned does exit if an unexpected error occurs)
|
|
<BR>
|
|
and add a function in sane-net (may be supported by saned)
|
|
<BR>
|
|
that makes it possible to find out if saned has exit.
|
|
<BR>
|
|
Then we can add an error code SANE_STATUS_NETWORK_CONNECTION_LOST
|
|
<BR>
|
|
or something like that and the frontend will be able to inform
|
|
<BR>
|
|
the user about it.
|
|
<BR>
|
|
<P>Bye
|
|
<BR>
|
|
Oliver
