CPXNETgetarcnodes

Description

The function CPXNETgetarcnodes() is used to access the "from nodes" and "to nodes" for a range of arcs in the network stored in a CPLEX network problem object.

Return Value

If the operation is successful, CPXNETgetarcnodes() returns the value 0; if not, it returns a nonzero value to indicate an error.

Synopsis

int CPXNETgetarcnodes (CPXENVptr env,
                       CPXNETptr net,
                       int *fromnode,
                       int *tonode,
                       int begin,
                       int end);

Arguments


CPXENVptr env

The pointer to the CPLEX environment as returned by one of the CPXopenCPLEX() routines.

CPXNETptr net

A pointer to a CPLEX network problem object as returned by CPXNETcreateprob().

int *fromnode

Array in which to write the "from node" indices of the requested arcs. If NULL is passed, no "from node" indices will be retrieved. Otherwise the size of the array must be(end-begin+1).

int *tonode

Array in which to write the "to node" indices of the requested arcs. If NULL is passed, no "to node" indices will be retrieved. Otherwise the size of the array must be(end-begin+1).

int begin

Index of the first arc to get nodes for.

int end

Index of the last arc to get nodes for.

Example

status = CPXNETgetarcnodes (env, net, fromnode, tonode,
                            0, cur_narcs);
