<?php
/** PLEASE NOTE THIS EXAMPLE WILL CAUSE THE PROCESS TO HANG **/
$mutex = Mutex::create(true);
/** You cannot use the "new" keyword, a Cond is not a PHP object **/
$cond = Cond::create();
/** The caller must lock the associated Mutex before a call to broadcast **/

Cond::destroy($cond);
Mutex::unlock($mutex);
Mutex::destroy($mutex);
