XSLPsetfunctionerror

---

Purpose

Set the function error flag for the problem

Synopsis

int XPRS_CC XSLPsetfunctionerror(XSLPprob Prob);

Argument

Prob	The current SLP problem.

Example

The following example from within a user function sets the function error flag if there is an error during the function evaluation:

double XPRS_CC ProfitCalc(double *Value, int *ArgInfo) {
  XSLPprob Prob;
  double Factor, Size;
  Factor = Value[0];
  Size = Value[1];
  if (Factor < 0) {
    XSLPgetfuncobject(ArgInfo, XSLP_XSLPPROBLEM, &Prob);
    XSLPsetfunctionerror(Prob);
    return 0.0;
  }
  return pow(Factor,Size);
}

Note the use of XSLPgetfuncobject to retrieve the Xpress-SLP problem.

Further information

Once the function error has been set, calculations generally stop and the routines will return to their caller with a nonzero return code.
