Get program scheduling priority. The value *which* is one of
:const:`PRIO_PROCESS`, :const:`PRIO_PGRP`, or :const:`PRIO_USER`, and *who*
is interpreted relative to *which* (a process identifier for
:const:`PRIO_PROCESS`, process group identifier for :const:`PRIO_PGRP`, and a

(respectively) the calling process, the process group of the calling process,
or the real user ID of the calling process.

.. function:: setpriority(which, who, priority)
.. index:: single: process; scheduling priority
Set program scheduling priority. The value *which* is one of
:const:`PRIO_PROCESS`, :const:`PRIO_PGRP`, or :const:`PRIO_USER`, and *who*
is interpreted relative to *which* (a process identifier for
:const:`PRIO_PROCESS`, process group identifier for :const:`PRIO_PGRP`, and a
user ID for :const:`PRIO_USER`). A zero value for *who* denotes
(respectively) the calling process, the process group of the calling process,
or the real user ID of the calling process.
*priority* is a value in the range -20 to 19. The default priority is 0;
lower priorities cause more favorable scheduling.
