Function IpoptSolveWarmStart 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn IpoptSolveWarmStart(
    ipopt_problem: IpoptProblem,
    x: *mut Number,
    g: *mut Number,
    obj_val: *mut Number,
    mult_g: *mut Number,
    mult_x_L: *mut Number,
    mult_x_U: *mut Number,
    bound_status_in: *const IpoptBoundStatus,
    cons_status_in: *const IpoptConsStatus,
    bound_status_out: *mut IpoptBoundStatus,
    cons_status_out: *mut IpoptConsStatus,
    user_data: *mut c_void,
) -> Index

Convenience one-shot: equivalent to IpoptSetWarmStartWorkingSet + IpoptSolve + IpoptGetWorkingSet in sequence. The input/output working-set buffers are independent (so a caller can read back the new working set into the same array used as input). Pass NULL for any in/out buffer to skip that side.

Returns the ApplicationReturnStatus integer, identical to IpoptSolve.

Safety

All pointer arguments follow the same contract as IpoptSolve plus the working-set buffer sizes documented on IpoptSetWarmStartWorkingSet / IpoptGetWorkingSet.
