We have a batch file that we are running to script some xperf analysis.
We are trying to trace calls to SetThreadExecutionState(). Then we run
the below trace and we get nothing. We have an app that we are pretty
sure is calling SetThreadExecutionState() properly as it prevents the
system from going to sleep. Anyone know what we are not doing right in
the batch file?
Thanks,
Tom
