3.16 Void

An XDR void is a 0-byte quantity. Voids are useful for describing operations that take no data as input or no data as output. They are also useful in unions, where some arms may contain data and others do not. The declaration is simply as follows:

         void;

Voids are illustrated as follows:

           ++
           ||                                                     VOID
           ++
         --><-- 0 bytes
