# 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.

成功回傳`TRUE`失敗回傳`FALSE`。
