<h3 class="section">8.8 The ‘<samp>@</samp>’ Type Descriptor</h3>
|
|
<p>The ‘<samp>@</samp>’ type descriptor is used for a
|
pointer-to-non-static-member-data type. It is followed
|
by type information for the class (or union), a comma, and type
|
information for the member data.
|
</p>
|
<p>The following C<tt>++</tt> source:
|
</p>
|
<div class="smallexample">
|
<pre class="smallexample">typedef int A::*int_in_a;
|
</pre></div>
|
|
<p>generates the following stab:
|
</p>
|
<div class="smallexample">
|
<pre class="smallexample">.stabs "int_in_a:t20=21=@19,1",128,0,0,0
|
</pre></div>
|
|
<p>Note that there is a conflict between this and type attributes
|
(see <a href="String-Field.html#String-Field">String Field</a>); both use type descriptor ‘<samp>@</samp>’.
|
Fortunately, the ‘<samp>@</samp>’ type descriptor used in this C<tt>++</tt> sense always
|
will be followed by a digit, ‘<samp>(</samp>’, or ‘<samp>-</samp>’, and type attributes
|
never start with those things.
