Function SCIPsolveBendersSubproblem 

pub unsafe extern "C" fn SCIPsolveBendersSubproblem(
    scip: *mut SCIP,
    benders: *mut SCIP_BENDERS,
    sol: *mut SCIP_SOL,
    probnumber: c_int,
    infeasible: *mut c_uint,
    solvecip: c_uint,
    objective: *mut f64,
) -> SCIP_RETCODE

calls the solving method for a single Benders’ decomposition subproblem

The method either calls the users solve subproblem method or calls the generic method. In the case of the generic method, the user must set up the subproblem prior to calling this method.

@return \ref SCIP_OKAY is returned if everything worked. Otherwise a suitable error code is passed. See \ref SCIP_Retcode “SCIP_RETCODE” for a complete list of error codes.

@pre This method can be called if SCIP is in one of the following stages: - \ref SCIP_STAGE_INITPRESOLVE - \ref SCIP_STAGE_PRESOLVING - \ref SCIP_STAGE_EXITPRESOLVE - \ref SCIP_STAGE_PRESOLVED - \ref SCIP_STAGE_INITSOLVE - \ref SCIP_STAGE_SOLVING - \ref SCIP_STAGE_SOLVED
