(PHP 5)

pcntl_getpriority -- Get the priority of any process

## Description

int pcntl_getpriority ( [int pid [, int process_identifier]] )

pcntl_getpriority() gets the priority of `pid`. If `pid` is not specified, the pid of the current process is used. Because priority levels can differ between system types and kernel versions, please see your system's getpriority(2) man page for specific details.

pcntl_getpriority() returns the priority of the process or `FALSE` on error. A lower numerical value causes more favorable scheduling.

`process_identifier` is one of `PRIO_PGRP`, `PRIO_USER` or `PRIO_PROCESS`.

Внимание
Эта функция может возвращать как логическое значение `FALSE`, так и не относящееся к логическому типу значение, которое приводится к `FALSE`, например, `0` или "". За более подробной информации обратитесь к разделу Булев тип. Используйте оператор === для проверки значения, возвращаемого этой функцией.
