Function SCIPaddConsLocks 

pub unsafe extern "C" fn SCIPaddConsLocks(
    scip: *mut SCIP,
    cons: *mut SCIP_CONS,
    nlockspos: c_int,
    nlocksneg: c_int,
) -> SCIP_RETCODE

adds given values to lock status of the constraint and updates the rounding locks of the involved variables

@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 @p scip is in one of the following stages: - \ref SCIP_STAGE_PROBLEM - \ref SCIP_STAGE_TRANSFORMING - \ref SCIP_STAGE_INITPRESOLVE - \ref SCIP_STAGE_PRESOLVING - \ref SCIP_STAGE_EXITPRESOLVE - \ref SCIP_STAGE_INITSOLVE - \ref SCIP_STAGE_SOLVING - \ref SCIP_STAGE_EXITSOLVE - \ref SCIP_STAGE_FREETRANS
