[Coin-lpsolver] Clp message

[Francois Margot]

John:

I use the following code:

#include <cstdio>
#include<stdlib.h>
#include <cfloat>

#include "OsiSolverInterface.hpp"
#include "OsiSolverParameters.hpp"
#include "OsiClpSolverInterface.hpp"

int main() 
{
   char f_name_lp[256];

   printf("Name of the input file (.lp/.mps):\n");
   scanf("%s", f_name_lp);

   OsiClpSolverInterface *clp = new OsiClpSolverInterface;
   clp->messageHandler()->setLogLevel(0);
   clp->readMps(f_name_lp);
   clp->initialSolve();
}

It prints:

Name of the input file (.lp/.mps):
bac.mps
Coin0001I At line 1 NAME
Coin0001I At line 2 ROWS
Coin0001I At line 20 COLUMNS
Coin0001I At line 50 RHS
Coin0001I At line 59 BOUNDS
Coin0001I At line 70 ENDATA
Coin0002I Problem no_name has 16 rows, 10 columns and 38 elements
Coin0511I After Postsolve, objective -3.5, infeasibilities - dual 0 (0), primal 0 (0)

After changing 511,1 to 511,2 in CoinMessage.cpp, the message is not printed 
anymore. An explanation about how the CoinMessage works in relation to Clp
log level would be welcome.
