This function returns the name of the function being probed
based on the current address, as computed by symname(<code class="function">addr</code>) or
usymname(<code class="function">uaddr</code>) depending on probe context (whether the probe is
a user probe or a kernel probe).
</p></div><div class="refsect1"><a name="idp144836780"></a><h2>Please note</h2><p>
this function's behaviour differs between SystemTap 2.0
and earlier versions. Prior to 2.0, <code class="function">probefunc</code> obtained the function
name from the probe point string as returned by <code class="function">pp</code>, and used the
current address as a fallback.
