int CPXPUBLIC CPXNETchgarcnodes(CPXCENVptr env, CPXNETptr net, int cnt, const int * indices, const int * fromnode, const int * tonode)

Definition file: cplex.h

The routine CPXNETchgarcnodes can be used to change the nodes for a set of arcs in the network stored in a network problem object.

Any solution information stored in the problem object is lost.

Example

 status = CPXNETchgarcs (env, net, cnt, indices, newfrom, newto);

env	A pointer to the CPLEX environment as returned by `CPXopenCPLEX`.
net	A pointer to a CPLEX network problem object as returned by `CPXNETcreateprob`.
cnt	Number of arcs to change.
indices	An array of arc indices that indicate the arcs to be changed. This array must have a length of at least `cnt`. All indices must be in the range [`0, narcs-1`].
fromnode	An array of indices of the “from node” for which the arcs are to be changed. All indices must be in the range [`0, nnodes-1`]. The size of the array must be at least `cnt`.
tonode	An array of indices of the “to node” for which the arcs are to be changed. All indices must be in the range [`0, nnodes-1`]. The size of the array must be at least `cnt`.

The routine returns zero on success and nonzero if an error occurs.
