dtrace discuss - May 2007 - how to do tracing in user process.

Hello,
 
I wanted to enable tracing in user process.
but following example from guide is not working.
 
pid$1::$2:entry
{
self->trace = 1;
}
pid$1::$2:return
/self->trace/
{
self->trace = 0;
}
pid$1:::entry,
pid$1:::return
/self->trace/
{
}
 
I am getting error like invalid probe description ..... undefined macro variable
in probe description.
 
pid$target:user lib:user function:entry
 
Any idea what I am doing wrong.
Do I need to enable probe first and then call?
 
TIA
Vineet

how are you calling this?

Recursion, n.: see ''Recursion''

Vineet, the "macro variables" are the $1 and $2, and they''re
arguments
to the dtrace script

What this *wants* is something like

./script.d PID functionname

where PID is a process ID of a running process, and functionname is an
entry point name.

So, while it might not tell you anything much useful, for example you could use

# ./script.d $$ read
