  62. <h4 class="subsection">5.2.3 Lines for a Function&rsquo;s Subroutines</h4>
  63. <p>A function&rsquo;s entry has a line for each of its subroutines&mdash;in other
  64. words, a line for each other function that it called. These lines&rsquo;
  65. fields correspond to the fields of the primary line, but their meanings
  66. are different because of the difference in context.
  67. </p>
  68. <p>For reference, we repeat two lines from the entry for the function
  69. <code>main</code>, the primary line and a line for a subroutine, together
  70. with the heading line that shows the names of the fields:
  71. </p>
  72. <div class="smallexample">
  73. <pre class="smallexample">index % time self children called name
  74. &hellip;
  75. [2] 100.0 0.00 0.05 1 main [2]
  76. 0.00 0.05 1/1 report [3]
  77. </pre></div>
  78. <p>Here are the meanings of the fields in the subroutine-line for <code>main</code>
  79. calling <code>report</code>:
  80. </p>
  81. <dl compact="compact">
  82. <dt><code>self</code></dt>
  83. <dd><p>An estimate of the amount of time spent directly within <code>report</code>
  84. when <code>report</code> was called from <code>main</code>.
  85. </p>
  86. </dd>
  87. <dt><code>children</code></dt>
  88. <dd><p>An estimate of the amount of time spent in subroutines of <code>report</code>
  89. when <code>report</code> was called from <code>main</code>.
  90. </p>
  91. <p>The sum of the <code>self</code> and <code>children</code> fields is an estimate
  92. of the total time spent in calls to <code>report</code> from <code>main</code>.
  93. </p>
  94. </dd>
  95. <dt><code>called</code></dt>
  96. <dd><p>Two numbers, the number of calls to <code>report</code> from <code>main</code>
  97. followed by the total number of non-recursive calls to <code>report</code>.
  98. This ratio is used to determine how much of <code>report</code>&rsquo;s <code>self</code>
  99. and <code>children</code> time gets credited to <code>main</code>.
  100. See <a href="Assumptions.html#Assumptions">Estimating <code>children</code> Times</a>.
  101. </p>
  102. </dd>
  103. <dt><code>name</code></dt>
  104. <dd><p>The name of the subroutine of <code>main</code> to which this line applies,
  105. followed by the subroutine&rsquo;s index number.
  106. </p>
  107. <p>If the caller is part of a recursion cycle, the cycle number is
  108. printed between the name and the index number.
