<h3 class="section">8.7 The &lsquo;<samp><span class="samp">#</span></samp>&rsquo; Type Descriptor</h3>
<p>This is used to describe a class method. This is a function which takes
an extra argument as its first argument, for the <code>this</code> pointer.
<p>If the &lsquo;<samp><span class="samp">#</span></samp>&rsquo; is immediately followed by another &lsquo;<samp><span class="samp">#</span></samp>&rsquo;, the second
one will be followed by the return type and a semicolon. The class and
argument types are not specified, and must be determined by demangling
the name of the method if it is available.
<p>Otherwise, the single &lsquo;<samp><span class="samp">#</span></samp>&rsquo; is followed by the class type, a comma,
the return type, a comma, and zero or more parameter types separated by
commas. The list of arguments is terminated by a semicolon. In the
debugging output generated by gcc, a final argument type of <code>void</code>
indicates a method which does not take a variable number of arguments.
If the final argument type of <code>void</code> does not appear, the method
was declared with an ellipsis.
<p>Note that although such a type will normally be used to describe fields
in structures, unions, or classes, for at least some versions of the
compiler it can also be used in other contexts.
