CPXNETgetpi

int CPXPUBLIC CPXNETgetpi(CPXCENVptr env, CPXCNETptr net, double * pi, int begin, int end)

Definition file: cplex.h

The routine CPXNETgetpi is used to access dual values for a range of nodes in the network stored in a network problem object.

For this function to succeed, a solution must exist for the problem object.

Example

 status = CPXNETgetpi (env, net, pi, 10, 20);

env	A pointer to the CPLEX environment as returned by `CPXopenCPLEX`.
net	A pointer to a CPLEX network problem object as returned by `CPXNETcreateprob`.
pi	Array in which to write solution dual values for requested nodes. If NULL is passed, no data is returned. Otherwise, `pi` must point to an array of size at least (`end-begin+1`).
begin	Index of the first node for which the dual value is to be obtained.
end	Index of the last node for which the dual value is to be obtained.

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