<dd><p>Display information about the tracepoint <var>num</var>.  If you don&rsquo;t
specify a tracepoint number, displays information about all the
tracepoints defined so far.  The format is similar to that used for
<code>info breakpoints</code>; in fact, <code>info tracepoints</code> is the same
command, simply restricting itself to tracepoints.
</p>
<p>A tracepoint&rsquo;s listing may include additional information specific to
tracing:
</p>
<ul>
<li> its passcount as given by the <code>passcount <var>n</var></code> command

</li><li> the state about installed on target of each location
</li></ul>
