# pcntl_setpriority

(PHP 5)

pcntl_setpriority -- Change the priority of any process

## Description

bool pcntl_setpriority ( int priority [, int pid])

pcntl_setpriority() sets the priority of `pid` to `priority`. If `pid` is not specified, the pid of the current process is used.

`priority` is generally a value in the range `-20` to `20`. The default priority is `0` while a lower numerical value causes more favorable scheduling. Because priority levels can differ between system types and kernel versions, please see your system's setpriority(2) man page for specific details.

성공일 경우 `TRUE`를, 실패일 경우 `FALSE`를 반환합니다.
