The routine CPXNETdelarcs is used to remove a range of
 arcs from the network stored in a network problem object. The remaining arcs
 are renumbered starting at zero; their order is preserved. If removing arcs
 disconnects some nodes from the rest of the network, the disconnected nodes
 remain part of the network.
Any solution information stored in the problem object is lost.
Example
status = CPXNETdelarcs (env, net, 10, 20);
| env | A pointer to the CPLEX environment as returned by   | 
| net | A pointer to a CPLEX network problem object as returned by   | 
| begin | Index of the first arc to be deleted.  | 
| end | Index of the last arc to be deleted.  |
