<h4 class="subsection">5.2.3 Lines for a Function&rsquo;s Subroutines</h4>

<p>A function&rsquo;s entry has a line for each of its subroutines&mdash;in other
words, a line for each other function that it called.  These lines&rsquo;
fields correspond to the fields of the primary line, but their meanings
are different because of the difference in context.
</p>
<p>For reference, we repeat two lines from the entry for the function
<code>main</code>, the primary line and a line for a subroutine, together
with the heading line that shows the names of the fields:
</p>
<div class="smallexample">
<pre class="smallexample">index  % time    self  children called     name
&hellip;
[2]    100.0    0.00    0.05       1         main [2]
                0.00    0.05       1/1           report [3]
</pre></div>

<p>Here are the meanings of the fields in the subroutine-line for <code>main</code>
calling <code>report</code>:
</p>
<dl compact="compact">
<dt><code>self</code></dt>
<dd><p>An estimate of the amount of time spent directly within <code>report</code>
when <code>report</code> was called from <code>main</code>.
</p>
</dd>
<dt><code>children</code></dt>
<dd><p>An estimate of the amount of time spent in subroutines of <code>report</code>
when <code>report</code> was called from <code>main</code>.
</p>
<p>The sum of the <code>self</code> and <code>children</code> fields is an estimate
of the total time spent in calls to <code>report</code> from <code>main</code>.
</p>
</dd>
<dt><code>called</code></dt>
<dd><p>Two numbers, the number of calls to <code>report</code> from <code>main</code>
followed by the total number of non-recursive calls to <code>report</code>.
This ratio is used to determine how much of <code>report</code>&rsquo;s <code>self</code>
and <code>children</code> time gets credited to <code>main</code>.
See <a href="Assumptions.html#Assumptions">Estimating <code>children</code> Times</a>.
</p>
</dd>
<dt><code>name</code></dt>
<dd><p>The name of the subroutine of <code>main</code> to which this line applies,
followed by the subroutine&rsquo;s index number.
</p>
<p>If the caller is part of a recursion cycle, the cycle number is
printed between the name and the index number.
</p></dd>
</dl>
