The routine CPXNETgetarcnodes is used to access the
 from-nodes and to-nodes for a range of arcs in
 the network stored in a network problem object.
Example
 status = CPXNETgetarcnodes (env, net, fromnode, tonode,
                             0, cur_narcs-1);| env | A pointer to the CPLEX environment as returned by   | 
| net | A pointer to a CPLEX network problem object as returned by   | 
| fromnode | Array in which to write the from-node indices of the requested arcs. If NULL is passed, no from-node indices are retrieved. Otherwise, the size of the array must be (  | 
| tonode | Array in which to write the to-node indices of the requested arcs. If NULL is passed, no to-node indices are retrieved. Otherwise, the size of the array must be (  | 
| begin | Index of the first arc to get nodes for.  | 
| end | Index of the last arc to get nodes for.  |
