# function::probefunc(3stap)

Return the probe point's function name, if known

## NAME

function::probefunc - Return the probe point's function name, if known

## SYNOPSIS

```
    probefunc:string()
```

## ARGUMENTS

None

## DESCRIPTION

This function returns the name of the function being probed based on the current address, as computed by symname(**addr**) or usymname(**uaddr**) depending on probe context (whether the probe is a user probe or a kernel probe).

## PLEASE NOTE

this function's behaviour differs between SystemTap 2.0 and earlier versions. Prior to 2.0, **probefunc** obtained the function name from the probe point string as returned by **pp**, and used the current address as a fallback.

Consider using **ppfunc** instead.
