Gets the next node in a list.

Node *NextNode( const Node *n )

This macro gets a pointer to the next node in a list. If the current node is the last node in the list, the result is a pointer to the tail (end-of-list) anchor. To determine if the return value is an actual node rather than the tail anchor, call the IsNode() procedure.

Example 1: Use of NextNode in forward list traversal

for (n = FirstNode( l ); IsNode( l, n ); n = NextNode( n )) 
{   . . .   }; 

• n Pointer to the current node.

The macro returns a pointer to the next node in the list or, if the current node is the last node in the list, to the tail (end-of-list) anchor.

Macro implemented in list.h V20.

• list.h ANSI C Macro definition

Assumes that n is a node in a list. If not, watch out.
