pcntl_getpriority — Get the priority of any process

### Description

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

pcntl_getpriority() gets the priority of `pid` . Because priority levels can differ between system types and kernel versions, please see your system's getpriority(2) man page for specific details.

### Parameters

`pid`

  If not specified, the pid of the current process is used.

`process_identifier`

  One of `PRIO_PGRP`, `PRIO_USER` or `PRIO_PROCESS`.

### Return Values

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

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.
