<h3 class="section">8.2 Defining a Symbol Within Another Type</h3>

<p>In C<tt>++</tt>, a symbol (such as a type name) can be defined within another type. 
<!-- FIXME: Needs example. -->

   <p>In stabs, this is sometimes represented by making the name of a symbol
which contains &lsquo;<samp><span class="samp">::</span></samp>&rsquo;.  Such a pair of colons does not end the name
of the symbol, the way a single colon would (see <a href="String-Field.html#String-Field">String Field</a>).  I'm
not sure how consistently used or well thought out this mechanism is. 
So that a pair of colons in this position always has this meaning,
&lsquo;<samp><span class="samp">:</span></samp>&rsquo; cannot be used as a symbol descriptor.

   <p>For example, if the string for a stab is &lsquo;<samp><span class="samp">foo::bar::baz:t5=*6</span></samp>&rsquo;,
then <code>foo::bar::baz</code> is the name of the symbol, &lsquo;<samp><span class="samp">t</span></samp>&rsquo; is the
symbol descriptor, and &lsquo;<samp><span class="samp">5=*6</span></samp>&rsquo; is the type information.
