  64. <h3 class="section">8.2 Defining a Symbol Within Another Type</h3>
  65. <p>In C<tt>++</tt>, a symbol (such as a type name) can be defined within another type.
  66. </p>
  67. <p>In stabs, this is sometimes represented by making the name of a symbol
  68. which contains &lsquo;<samp>::</samp>&rsquo;. Such a pair of colons does not end the name
  69. of the symbol, the way a single colon would (see <a href="String-Field.html#String-Field">String Field</a>). I&rsquo;m
  70. not sure how consistently used or well thought out this mechanism is.
  71. So that a pair of colons in this position always has this meaning,
  72. &lsquo;<samp>:</samp>&rsquo; cannot be used as a symbol descriptor.
  73. </p>
  74. <p>For example, if the string for a stab is &lsquo;<samp>foo::bar::baz:t5=*6</samp>&rsquo;,
  75. then <code>foo::bar::baz</code> is the name of the symbol, &lsquo;<samp>t</samp>&rsquo; is the
  76. symbol descriptor, and &lsquo;<samp>5=*6</samp>&rsquo; is the type information.
