Hi Corey,
Thanks for the patch. It is working well now. Now we are able to get the
current value of the sensor in the input parameters of the event handler
function.
Is this a official patch? When will it be included in the main source?
thanks and regards
S Sarath

Hmm, I think I see a bug. Can you try the attached patch?
If that doesn't work, can you print out the raw values of the bytes in
event and the value_present value and send them to me? I should be able
to tell from that. To get the data, call data =
ipmi_event_get_data_ptr(info->event); and dump 13 bytes from data.
If you look in table 32-1 in the spec, it has the layout of an event.
The event data is what we are really interested in. Table 29-6 in the
spec give the format of the event data. We are particularly interested
in event data 1. If bytes [5:4] in event data 1 is not 01b, then that
is saying that there is no value in the event. If that is the case, the
library should set value_present to IPMI_NO_VALUES_PRESENT, depending on
whether it could convert the event. I had a "2" instead of a "1" there.
