CPXcheckaddcols

Description

The routine CPXcheckaddcols() validates the arguments of the corresponding CPXaddcols() routine. This data checking routine is found in source format in the file check.c which is provided with the standard CPLEX distribution. To call this routine, you must compile and link check.c with your program as well as the CPLEX Callable Library.

The routine returns a nonzero if it detects an error in the data; it returns a zero if it does not detect any data errors.

int CPXcheckaddcols (CPXCENVptr env, CPXCLPptr lp, int ccnt, int nzcnt, const double *obj, const int *cmatbeg, const int *cmatind, const double *cmatval, const double *lb, const double *ub, char **colname);

Arguments

The CPXcheckaddcols() routine has the same argument list as the CPXaddcols() routine. The second argument, lp, is technically a pointer to a constant LP object of type CPXCLPptr rather than type CPXLPptr, as this routine will not modify the model. For most user applications, this distinction is unimportant.

status = CPXcheckaddcols (env, lp, ccnt, nzcnt, obj, cmatbeg, cmatind, cmatval, lb, ub, newcolname);
