# function::thread\_indent\_depth(3stap)

returns the nested-depth of the current task

## NAME

function::thread\_indent\_depth - returns the nested-depth of the current task

## SYNOPSIS

```
    thread_indent_depth:long(delta:long)
```

## ARGUMENTS

*delta*

the amount of depth added/removed for each call

## DESCRIPTION

This function returns an integer equal to the nested function-call depth starting from the outermost initial level. This function is useful for saving space (consumed by whitespace) in traces with long nested function calls. Use this function in a similar fashion to **thread\_indent**, i.e., in call-probe, use thread\_indent\_depth(1) and in return-probe, use thread\_indent\_depth(-1)
