When the current running task isn't a user space thread, or the address cannot be found, zero is returned. Can be used to see where the current task is combined with <code class="function">usymname</code> or <code class="function">symdata</code>. Often the task will be in the VDSO where it entered the kernel. FIXME - need VDSO tracking support #10080. </p></div></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="re24.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="ch02.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="re26.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top"><span>function::stack_unused</span> </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> <span>function::cmdline_args</span></td></tr></table></div></body></html>
