Hi Angelo,
great thanks. It's working a bit better now. I assume that ustackdepth
handles functions with no return statements? These would otherwise be
missed by using a variable to track depth with a return probe.
One thing is the flow indent still seems off. Do you know of any
workaround for that?
Cheers,
Max

Hey Max:
There is a built in variable ustackdepth that should provide you
stack depth in user land. See if this helps

Hi Folks,
I'm trying to use DTrace to understand some complex code using the
user process probe.
Things are basically not matching up. When I use a variable to
track depth, sometimes it jumps. Similarly, the flow indent seems
off.
I read another post saying that this is caused by missing return
statements in functions.
http://mail.opensolaris.org/pipermail/dtrace-discuss/2005-June/000011.html
Problem is I'm a bit of a newbie with DTrace so although I get the
general idea of the post, I'm still a bit confused about how to do
a workaround.
Would anyone have any advice on how to resolve this?
Ideally I'm just after a way to reliably trace function entries and
returns.
Any advice would be much appreciated.
Thanks,
Max
