[OS] How to get basic/non-basic variable information from the OSResult or OSRL ?

[Chen K★Pop Dangsuwan]

Hello

I've created the OSInstance and solved it with the CoinSolver object.
It can solve correctly but I can't get basic/non-basic variable information from the OSResult or OSRL.
The OSOption is default.

Here is the code.
--------------------------------------------------------------
OSInstance *osin = createOSInstance();

CoinSolver *solver = new CoinSolver();
solver->osinstance = osin;
solver->solve();

OSResult *osr = solver->osresult;
int numOfBasisVar = osr->getNumberOfBasisVar(0);
--------------------------------------------------------------

numOfBasisVar is -1 for every model I've solved.

I appreciate any help on this matter.

Best regards
