The nniiccee() function obtains the scheduling priority of the process from
the system and sets it to the priority value specified in _i_n_c_r. The pri
ority is a value in the range 20 to 20. The default priority is 0; low
er priorities cause more favorable scheduling. Only the superuser may
lower priorities.
Children inherit the priority of their parent processes via fork(2).
