 @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
