Monitoring uevents at the user space

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello All,

I am writing a driver for OMAP4460 thermal sensor. I have a requirement
to send events to the user space from the driver on some condition.

I am using kobject_uevent(&temp_sensor->dev->kobj, KOBJ_ADD) as
part of initialization.

On the occurrence of the event i am notifying via
kobject_uevent(&temp_sensor->dev->kobj, KOBJ_CHANGE).

I am using busybox file system. What is the recommended way
to actually verify whether the uevent has been propagated to the
user space or not from the driver?
