[etherlab-users] Registering domains while master is activated

[hamelin.philippe at ireq.ca]

Hi,

The reason for that is that I may have a variable topology, i.e. add nodes to a system that is running. Hence, I would like to be able to configure new domains while not interrupting the current process data tranfers. Indeed, activating/deactivatint the master won't help.

Best regards,

Philippe Hamelin

No, you are right. Creating domains and registering process data objects for them require memory allocations, and therefore are not possible in realtime. But you can use ecrt_master_deactivate() and supply the new configuration, and the ecrt_master_activate() again.
But that will interrupt process data transfer and won't help you, will it?

Why do you want to create domains during realtime?
