  69. 

  70. <p>In C<tt>++</tt>, a symbol (such as a type name) can be defined within another type.

  71. </p>

  72. <p>In stabs, this is sometimes represented by making the name of a symbol

  73. which contains &lsquo;<samp>::</samp>&rsquo;.  Such a pair of colons does not end the name

  74. of the symbol, the way a single colon would (see <a href="String-Field.html#String-Field">String Field</a>).  I&rsquo;m

  75. not sure how consistently used or well thought out this mechanism is.

  76. So that a pair of colons in this position always has this meaning,

  77. &lsquo;<samp>:</samp>&rsquo; cannot be used as a symbol descriptor.

  78. </p>

  79. <p>For example, if the string for a stab is &lsquo;<samp>foo::bar::baz:t5=*6</samp>&rsquo;,

  80. then <code>foo::bar::baz</code> is the name of the symbol, &lsquo;<samp>t</samp>&rsquo; is the

  81. symbol descriptor, and &lsquo;<samp>5=*6</samp>&rsquo; is the type information.

  82. </p>
