 * Values of the auto variables disappear when the
 * function returns.  Therefore reference values 
 * which are to be returned to the client must be 
 * of type static or malloc'ed.
 *
 * Pointer chasing is automatic.  This example is 
 * for illustrative purpose only.  Generally, lots 
 * of pointer to pointer to the nth degree is not 
 * a good idea.
 *
 * Result is returned as a reference.
