Function ipsolve_ 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn ipsolve_(
    fproblem: *mut *mut c_void,
    x: *mut Number,
    g: *mut Number,
    obj_val: *mut Number,
    mult_g: *mut Number,
    mult_x_l: *mut Number,

ipsolve_(FProblem, X, G, OBJ_VAL, MULT_G, MULT_X_L, MULT_X_U, IDAT, DDAT) -> Index.

Safety

All pointer arguments must satisfy the contracts documented on crate::IpoptSolve. idat/ddat are scratch arrays passed back to the user’s Fortran callbacks.
