CPXgetlb

Description

The routine CPXgetlb() is used to access a range of lower bounds on the variables of a CPLEX problem object. The beginning and end of the range must be specified.

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

int CPXgetlb (CPXCENVptr env, CPXCLPptr lp, double *lb, int begin, int end);

Arguments

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

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

An array where the specified lower bounds on the variables are to be returned. This array must be of length at least (end - begin + 1). The lower bound of variable j is returned in lb[j - begin].

An integer indicating the beginning of the range of lower bounds to be returned.

An integer indicating the end of the range of lower bounds to be returned.

status = CPXgetlb (env, lp, lb, 0, cur_numcols-1);
