This is encoded in the <em class="parameter"><code>action</code></em> argument and the return value for
a <em class="parameter"><code>report_signal</code></em>() callback. It says what will happen to the
signal described by the <span class="structname">siginfo_t</span> parameter to the callback.
</p><p>
The <code class="constant">UTRACE_SIGNAL_REPORT</code> value is used in an <em class="parameter"><code>action</code></em> argument when
a tracing report is being made before dequeuing any pending signal.
If this is immediately after a signal handler has been set up, then
<code class="constant">UTRACE_SIGNAL_HANDLER</code> is used instead. A <em class="parameter"><code>report_signal</code></em> callback
that uses <code class="constant">UTRACE_SIGNAL_DELIVER</code>|<code class="constant">UTRACE_SINGLESTEP</code> will ensure
it sees a <code class="constant">UTRACE_SIGNAL_HANDLER</code> report.
