CPXNETgetarcnodes

int CPXPUBLIC CPXNETgetarcnodes(CPXCENVptr env, CPXCNETptr net, int * fromnode, int * tonode, int begin, int end)

Definition file: cplex.h

Include files: cplex.h

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);

Parameters:

env	A pointer to the CPLEX environment as returned by `CPXopenCPLEX`.
net	A pointer to a CPLEX network problem object as returned by `CPXNETcreateprob`.
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 (`end-begin+1`).
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 (`end-begin+1`).
begin	Index of the first arc to get nodes for.
end	Index of the last arc to get nodes for.

Returns:

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