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 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 problem. For most user applications, this distinction is unimportant.

Example

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