--- Comment #2 from cong <q1875486458 at gmail dot com> ---
is there any way to distinguish between
1. systemtap does not probe to correct process (which should not happen because
i set pid explicitly)
2. systemtap could not find those function which should probe
3. there is no event came out

since the method 1 i use in before code does not report any wran/erorr ,it
seems that it probe to correct process and find the debuginfo and find the
function i want to probe.  

a correspond conjecture is that: "is just no event came out".

did this logic chain make sense? or i just missing some point?
