Function IpoptSolverKktSolveScaled 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn IpoptSolverKktSolveScaled(
    solver: IpoptSolver,
    rhs: *const Number,
    lhs: *mut Number,
) -> Bool

IpoptSolverKktSolve without the natural-units correction: the back-solve runs in the solver’s internal scaled space. Identical to IpoptSolverKktSolve when no NLP scaling is active.

Safety

Same contract as IpoptSolverKktSolve.
