dtrace discuss - Aug 2007 - How to set indent level in flowindent.

I am diagnosing a hang. I know in what kernel routine the thread
hangs in (cv_wait_sig_swap) and I know what system call is made
that leads to the hang (connect). What I need to know is how it
gets from one the the other.

I am using speculations to capture the function call data and
then commiting it on entry to cv_wait_sig_swap. My problem is
that since this is a hang, the trace is not going to come out,
but I do want to capture as many of these as I can over a long
period of time.

So, what I want is when I do the commit and destroy the speculation
buffer, I also want to reset the indent level to zero. Is there any
way to tell the flowindent code to go back to no indent?

Hi Brian,

You can''t explicitly set the indentation level for the built-in
flowindent
support, but you call roll your own flowindent using printf().
