sleep,hibernate and user lock,unlock events

GNakul · 06-04-2012, 06:50 AM

Dear all,

Is it possible to programetically [using C] capture/record power events like sleep,hibernate and user lock,unlock events into a flat file.
I mean is there any such user space or kernel structure holding such data. Any such User or Kernel API?
Googled thoroughly didn't find any answers or sample code.I saw a couple of posts related to same issue, but didn't find any useful answer.

Thanks in advance for help.
Regards,
Nakul

I am not sure if I got your question correct but if you mean that you want the exact events taking place when the system is suspended,you can check the events occurring in the log file. For instance,the hibernation process can be checked in /var/log/pm-hibernate.log.
I am not sure about the log of user lock event though.
