Function Highs_getDualUnboundednessDirection 

Source 
pub unsafe extern "C" fn Highs_getDualUnboundednessDirection(
    highs: *const c_void,
    has_dual_unboundedness_direction: *mut HighsInt,
    dual_unboundedness_direction_value: *mut f64,
) -> HighsInt
Expand description

Indicates whether a dual unboundedness direction (corresponding to a certificate of primal infeasibility) exists, and (at the expense of solving an LP) gets it if it does not and dual_unboundedness_direction is not nullptr

@param highs A pointer to the Highs instance. @param has_dual_unboundedness_direction A pointer to a HighsInt to store 1 if the dual unboundedness direction exists. @param dual_unboundedness_direction_value An array of length [num_col] filled with the unboundedness direction.
