Within the io-net framework, how could a shared object, say a convertor
or down producer, be notified by the driver (up producer) of a fault
such as a disconnected cable? Would this be something that would be
driver specific (ie, not guaranteed to work in all cases) or would the
objects be required to poll the nicinfo periodically via a devctl()
call? I’m not sure if I’d like the latter possibility in the QNX
environment… so I hope there’s an [sig]event driven alternative.
Thanks,

Ping.
Please confirm one way or the other my suspicion that the only way to
determine that a cable might be disconnected is to poll for this
information periodically by way of a devctl() call to io-net?
Thanks,

Yes, that is correct.
