# 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.

Gibt bei Erfolg `TRUE` zurück, im Fehlerfall `FALSE`.
