<h4 class="subsection">5.2.3 Lines for a Function's Subroutines</h4>
<p>A function'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'
fields correspond to the fields of the primary line, but their meanings
are different because of the difference in context.
<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:
<pre class="smallexample"> index % time self children called name
...
[2] 100.0 0.00 0.05 1 main [2]
0.00 0.05 1/1 report [3]
</pre>
<p>Here are the meanings of the fields in the subroutine-line for <code>main</code>
calling <code>report</code>:
<dl>
<dt><code>self</code><dd>An estimate of the amount of time spent directly within <code>report</code>
when <code>report</code> was called from <code>main</code>.
<br><dt><code>children</code><dd>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>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>.
<br><dt><code>called</code><dd>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>'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>.
<br><dt><code>name</code><dd>The name of the subroutine of <code>main</code> to which this line applies,
followed by the subroutine's index number.
<p>If the caller is part of a recursion cycle, the cycle number is
printed between the name and the index number.
