Ok I didn't notice the libtracecmd, so I'll send the second patch against that since it's just against the event parse stuff. In reality all I need is the event parsing stuff, I just use the libtracecmd to open the trace.dat file. I'll see if I can figure out how to just parse the events live without having to record with trace-cmd first and that will probably be good enough for me for now, then maybe when I care about post-processing trace.dat you will have gotten to the bottom of your TODO list. Thanks,
Josef
