Function SCIPlpiGetSolFeasibility 

pub unsafe extern "C" fn SCIPlpiGetSolFeasibility(
    lpi: *mut SCIP_LPI,
    primalfeasible: *mut c_uint,
    dualfeasible: *mut c_uint,
) -> SCIP_RETCODE

gets information about primal and dual feasibility of the current LP solution

The feasibility information is with respect to the last solving call and it is only relevant if SCIPlpiWasSolved() returns true. If the LP is changed, this information might be invalidated.

Note that @p primalfeasible and @p dualfeasible should only return true if the solver has proved the respective LP to be feasible. Thus, the return values should be equal to the values of SCIPlpiIsPrimalFeasible() and SCIPlpiIsDualFeasible(), respectively. Note that if feasibility cannot be proved, they should return false (even if the problem might actually be feasible).
