Pointer Declarations
Pointer declarations are made in XDR exactly as they are in C.
The programmer cannot send pointers over a network, but can use
XDR pointers for sending recursive data types such as lists and trees.
In XDR language, the type is called optional-data, instead
of pointer. Pointer declarations have the following form
in XDR language:
pointer-declaration:
type-ident "*" variable-ident
An example of a pointer declaration is:
listitem *next; --> listitem *next;
