@node Method Type Descriptor
@section The @samp{#} Type Descriptor
This is like the @samp{f} type descriptor for functions (@pxref{Function
Types}), except that a function which uses the @samp{#} type descriptor
takes an extra argument as its first argument, for the @code{this}
pointer. The @samp{#} type descriptor is optionally followed by the
types of the arguments, then another @samp{#}. If the types of the
arguments are omitted, so that the second @samp{#} immediately follows
the @samp{#} which is the type descriptor, the arguments are being
omitted (to save space) and can be deduced from the mangled name of the
method. After the second @samp{#} there is type information for the
return type of the method and a semicolon.
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} pointer.
If the @samp{#} is immediately followed by another @samp{#}, 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.
Otherwise, the single @samp{#} 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}
indicates a method which does not take a variable number of arguments.
If the final argument type of @code{void} does not appear, the method
was declared with an ellipsis.
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
