Hi,

I'm writing Asyn driver that will interface our application daemon

running on Linux OS.

Application daemon is capable of emitting notifications that can tell

the client (asyn) that there is a change in value. Asyn driver would

register a callback to receive this notifications - everything is nice

and running till now, assuming that record SCAN field is set to I/O Intr

(camonitor refreshes value as expected).

How can I detect if user wants to change the SCAN field value to

Passive? This would in turn mean that we need to unregister from the

notifications that our application is sending and expect the user to do

caget like access.

Thank you!
Hinko
