The n
\bni
\bic
\bce
\be() function obtains the scheduling priority of the process from
the system and sets it to the priority value specified in _
\bi_
\bn_
\bc_
\br. 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 super-user may
Children inherit the priority of their parent processes via fork(2).
