format of .kev file  
Is the format of the .kev file documented somewhere?

Re: format of .kev file  
I don't think so.  What are you looking to do?

RE: format of .kev file  
I want to generate a file but not from QNX's API, from my own code without the need for the instrumented kernel. 
Obviously it would only contains USER EVENT but that is pretty much what I need.

Re: RE: format of .kev file  
In that case, you can rather use syslog in your application. How different it is going to be with the way you plan to 
use trace events?

Nanosecond precision,  no context switch,  each process has its record buffer greatly reducing resource contention (want
 to keep the 12 cores busy), no overhead for filtering unwanted event coming from other processes, portability.

For now I want to convert our data into a kev file to make use of the system profiler, but down the road ( many months 
as our GUI group is totally swamp with work, phew good thing, a few years back,  we choose not to used photon... I 
digress)  we will have our own application to display the data.
