int QSget_obj (QSprob p, double *obj)

This function returns the coefficients of the objective function as a dense vector, that is, all coefficients (both zero and non-zero) are returned in the array obj. The calling function must allocate the memory for the obj array; it should be of length at least ncols.

/* p is an initialized QSprob, a handle to an existing LP problem  */

int rval, ncols;
double *obj;

ncols = QSget_colcount (p);
obj = (double *) malloc (ncols * sizeof (double));

rval = QSget_obj (p, obj);
if (rval) {
    fprintf (stderr, 
             "Could not get objective, error code %d\n", rval);
} else {
    printf ("Objective Function\n");
    for (i = 0; i < ncols; i++) {
        printf ("%f\n", obj[i]);
    }
}

free (obj);
