<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 ‘<samp><span class="samp">::</span></samp>’. 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,
|
||
|
|
‘<samp><span class="samp">:</span></samp>’ cannot be used as a symbol descriptor.
|
||
|
|
|
||
|
|
<p>For example, if the string for a stab is ‘<samp><span class="samp">foo::bar::baz:t5=*6</span></samp>’,
|
||
|
|
then <code>foo::bar::baz</code> is the name of the symbol, ‘<samp><span class="samp">t</span></samp>’ is the
|
||
|
|
symbol descriptor, and ‘<samp><span class="samp">5=*6</span></samp>’ is the type information.
