# pcntl_getpriority

(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`.

Warning
This function may return Boolean `FALSE`, but may also return a non-Boolean value which evaluates to `FALSE`, such as 0 or "". Please read the section on Booleans for more information. Use the === operator for testing the return value of this function.
