How to get functions' local variables?

[HeTak]

Hi there,

My question is: How I can check a function's local varibales' value using
dtrace?

I'm a newbie in using dtrace and it's a bit weird for me..I went through
manuals and so, but did not get that. :(

What I could find out is that via args, I can get functions' input
arguments. But I could not find out how I can check the value of a variable
which is defined inside my goal function's scope. Isn't this feature
available in Dtrace?

Thanks :)
