node_bn* NthNode_bn ( | const nodelist_bn* nodes, int index )

Returns the node at position index within list nodes.

The numbering starts with 0, and goes to LengthNodeList_bn (nodes) - 1.

If index is less than 0, or greater than LengthNodeList_bn (nodes) - 1, NULL will be returned, and an error will be generated (unless it is LAST_ENTRY, which indicates the last node).

To recover the node by name, rather than index, see the suggestion in GetNodeNamed_bn.

For the inverse function (finding the index given the node) see the function IndexOfNodeInList_bn.

Version:

This function is available in all versions.

See also:

IndexOfNodeInList_bn |  | (inverse function) Return the index, given the node
SetNthNode_bn |  | Set the node at the given index
RemoveNthNode_bn |  | Remove the node from the list (also returns it)
LengthNodeList_bn |  | Find maximum node index

Example:

    The following function is available in NeticaEx.c:
    // Prints out the names of the nodes in the list passed to it.
    // You may need to print a newline ('\n') before the writing appears.
    //
    #include <stdio.h>

    void PrintNodeList (nodelist_bn* nodes){
        int i, numnodes = LengthNodeList_bn (nodes);
        for (i = 0;  i < numnodes;  ++i){
        if (i != 0)  printf (", ");
            printf ("%s", GetNodeName_bn (NthNode_bn (nodes, i)));
        }
    }
