CPXNETgetslack

int CPXPUBLIC CPXNETgetslack(CPXCENVptr env, CPXCNETptr net, double * slack, int begin, int end)

Definition file: cplex.h

Include files: cplex.h

The routine CPXNETgetslack is used to access slack values or, equivalently, violations of supplies/demands 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 = CPXNETgetslack (env, net, slack, 10, 20);

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`.
slack	Array in which to write solution slack variables for requested nodes. If NULL is passed, no data is returned. Otherwise, `slack` must point to an array of size at least (`end-begin+1`).
begin	Index of the first node for which a slack value is to be obtained.
end	Index of the last node for which a slack value is to be obtained.

Returns:

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