 A.2.2 How Variadic Functions are Defined and Used
 -------------------------------------------------
 
 Defining and using a variadic function involves three steps:
 
    * _Define_ the function as variadic, using an ellipsis (`...') in
      the argument list, and using special macros to access the variable
      arguments.   Receiving Arguments.
 
    * _Declare_ the function as variadic, using a prototype with an
      ellipsis (`...'), in all the files which call it.   Variadic
      Prototypes.
 
    * _Call_ the function by writing the fixed arguments followed by the
      additional variable arguments.   Calling Variadics.

 
* Variadic Prototypes  How to make a prototype for a function
 			  with variable arguments.
* Receiving Arguments  Steps you must follow to access the
 			  optional argument values.
* How Many Arguments   How to decide whether there are more arguments.
* Calling Variadics    Things you need to know about calling
 			  variable arguments functions.
* Argument Macros      Detailed specification of the macros
         		  for accessing variable arguments.
* Old Varargs          The pre-ISO way of defining variadic functions.
