I believe the original "hide run start / stop" was added specifically for ND280 GSC MIDAS. I do not know
why it was removed. "hide pause / resume" is still there. I will restore them. Hiding logger channel
section should probably be automatic of there is no /logger/channels, I can check if it works and what

Dear all,
I'm writing a very simple device driver starting from the nulldev.cxx
example.

The "multi" class driver takes care of that. It properly calls the SET and GET functions
with the correct index. The code for that is in multi.cxx:105:

Good evening,

Stefan is right. I forgot this. As solution to our troubles, mlogger is built without root support. use rmlogger instead.

No, I'm not aware of this problem, but I suspect that your events somehow got corrupted. You can try the mdump utility
or the "Event Dump" web page to peek into your events, maybe you see an issue there. To give you more detailed information,
I would have to reproduce your problem, which is probably hard without your hardware.

Good morning,
In our setup, we have a neutron detector that creates up to 16 MB of polled (EQ_POLLED) data in one event (event limit = 1) that we do not want to have |

I cannot confirm that. I just tried myself with examples/experiment/frontend.cxx, removed the RO_ODB, and the trigger events did NOT get copied to the ODB.
Actually you can debug the code yourself. The relevant line is in mfe.cxx:2075:
