12 This interface is obsoleted by setpriority(2).
13
14 The scheduling priority of the process is augmented by incr. Positive
15 priorities get less service than normal. Priority 10 is recommended to
16 users who wish to execute long-running programs without flak from the
17 administration.
18
19 Negative increments are ignored except on behalf of the super-user.
20 The priority is limited to the range -20 (most urgent) to 20 (least).
21
22 The priority of a process is passed to a child process by fork(2). For
23 a privileged process to return to normal priority from an unknown
24 state, nice should be called successively with arguments -40 (goes to
25 priority -20 because of truncation), 20 (to get to 0), then 0 (to main‐
26 tain compatibility with previous versions of this call).
