| <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. |
