[Cbc] multiple solutions with CbcMain

[Matthew Galati]

I switched to CbcMain from CbcModel.branchAndBound() based on comments
about performance.

I want to get multiple solutions from Cbc.

I am doing this:

   const char * argv[20];
   int   argc      = 0;
   string cbcExe   = "cbc";
   string cbcSolve = "-solve";
   string cbcQuit  = "-quit";
   string cbcLog   = "-log";
   string cbcLogSet= UtilIntToStr(debugLevel);
   string cbcMaxSave= "-maxSaved";
   string cbcMaxSaveSet= "100";

   argv[argc++] = cbcExe.c_str();
   argv[argc++] = cbcLog.c_str();
   argv[argc++] = cbcLogSet.c_str();
   argv[argc++] = cbcMaxSave.c_str();
   argv[argc++] = cbcMaxSaveSet.c_str();
   argv[argc++] = cbcSolve.c_str();
   argv[argc++] = cbcQuit.c_str();
   CbcModel cbc(*osiClp);


   CbcMain(argc, argv, cbc);


And from the log, I can tell there are multiple solutions.

Then, I tried to get them with:
int nSolutions = cbc.numberSavedSolutions();

But, it says there is only 1.

When I was using cbc.branchAndBound(), this access method worked fine.

How do I get the multiple solutions back when using CbcMain?
