# PERL setpriority Function

## Syntax

setpriority WHICH, WHO, PRIORITY

## Definition and Usage

Sets the priority for a process (PRIO_PROCESS), process group (PRIO_PGRP), or user (PRIO_USER). The argument WHICH specifies what entity to set the priority for, and WHO is the process ID or user ID to set. A value of 0 for WHO defines the current process, process group, or user. Produces a fatal error on systems that don.t support the system setpriority( ) function.

The priority is a number representing the level of priority (normally in the range 120 to 20) where the lower the priority the more favorable the scheduling of the process by the operating system.

## Return Value

- Nothing

## Example

    print("setpriority() ", setpriority(0, 0, -20), "\n");
