Hi, Jamal,

Now the genl utility can find the acpi event genetlink family.
And a simple user space demo is finished for handling acpi event.
I really appreciate your help. :)

np.

I think the patch which exposes ACPI events via netlink is ok.
But I still have some problems on
how to listen to specified genetlink family in user space?

I can get the dynamic id for "acpi_event" genl family.
But I don't know how to use this to receive messages from
specified genl family.
It seems that "#genl ctrl monitor" has something to do with this,
IMO, rtnl_open_byproto(&rth, nl_mgrp(GENL_ID_CTRL), NETLINK_GENERIC) is
used to receive messages from the nlctrl(controller) only, but
unfortunately it never works for me. :(

I dont have much time to look at your code given travel, but did you
try to use your group id instead of the controller's?
i.e:
rtnl_open_byproto(&rth, nl_mgrp(mydiscoveredacpiid), NETLINK_GENERIC)

If this doesnt work, ping me and i will take a look  - just expect some
latency in response.

cheers,
jamal
