Example

//create solver
BCalcDDS* solver = bcalcDDS_new("PBN", "N:.63.AKQ987.A9732 A8654.KQ5.T.QJT6 J973.J98742.3.K4 KQT2.AT.J6542.85", BCALC_NT, BCALC_PLAYER_NORTH);
if (solver != 0) exit(1);       //out of memory error
//use it, print player to play, and how many tricks his line can take:
printf("%c playes, and he with partner will be able to take %d tricks.\n",
        bcalc_playerSymbol(bcalcDDS_getPlayerToPlay(solver)),
        bcalcDDS_getTricksToTake(solver)
);
bcalcDDS_exec(solver, "7D x x");        //play 7 of dimamonds, and two smallest diamonds
//print current situation:
printf("%c playes, and he with partner will be able to take %d tricks.\n",
        bcalc_playerSymbol(bcalcDDS_getPlayerToPlay(solver)),
        bcalcDDS_getTricksToTake(solver)
);
bcalcDDS_delete(solver);        //and delete (free memory)

Names

All names defined by library have prefixes:

BCALC_ - consts (defines)
BCalc - types (for example: BCalcDDS)
bcalc - functions and macros
- bcalcDDS - functions which operates on BCalcDDS (almost all takes BCalcDDS* as first argument)
