[Help-glpk] Level of messages output

[Kai Sun]

My machine (Windows XP 32-bit) is running glpk 4.19.

I am having a problem dealing with control parameter, LPX_K_MSGLEV. I
set this parameter to 0 (no output) already. But I still get the same
output before. Does anyone know what is going on? Thanks!

Code:
        lpx_set_int_parm(lp, LPX_K_MSGLEV, 0);
        ret = lpx_get_int_parm(lp, LPX_K_MSGLEV);
        printf(" Output level = %d\n", ret);
        glp_simplex(lp, NULL);
Output:
 Output level = 0
*     0:   objval =  0.000000000e+000   infeas =  0.000000000e+000 (0)
*     2:   objval =  7.333333333e+002   infeas =  0.000000000e+000 (0)
