nice(2) adds ''inc'' to the nice value for the calling pid. (A large nice value means a low priority.) Only the super- user may specify a negative increment, or
priority increase.
!!RETURN VALUE
-On success, the new nice variable is returned. On failure -1 is returned. Since -1 is a valid return for nice(2), set errno to 0 before calling nice(3
), and check it's
value afterwards.
