<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.
</p>
<p>In stabs, this is sometimes represented by making the name of a symbol
which contains &lsquo;<samp>::</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&rsquo;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>:</samp>&rsquo; cannot be used as a symbol descriptor.
</p>
<p>For example, if the string for a stab is &lsquo;<samp>foo::bar::baz:t5=*6</samp>&rsquo;,
then <code>foo::bar::baz</code> is the name of the symbol, &lsquo;<samp>t</samp>&rsquo; is the
symbol descriptor, and &lsquo;<samp>5=*6</samp>&rsquo; is the type information.
</p>
