pcntl_setpriority() sets the priority of `pid`.

## Parâmetros

`priority`

  `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.

`pid`

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

`process_identifier`

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