Trace Driver using WPP macros

Hi

I am able to log traces in my driver using the WPP macros
and also read the traces using the Tracefmt utility.

I would like to write my own utility program to retrieve
the traces. So far I get the events from the driver using
OpenTrace() and ProcessTrace(). I am able to get our
messages that gets logged by the driver. However I am
interested to also know the time when the event occured.
This would require parsing the prefix added to each event.
Can you provide insight to as to how can I parse the
prefix that is appended to each event?

I want to convince my team that WPP is the latest and the
greatest technology from MS for tracing drivers.

Thanks
