How to use SWOOLE_IPC on process manager ?

[LAGGOUNE-Walid]

<?php

use Swoole\Process\Manager;
use Swoole\Process\Pool;

$pm = new Manager(SWOOLE_IPC_SOCKET);

$pm->add(function (Pool $pool, int $workerId) {
});

$pm->add(function (Pool $pool, int $workerId) {
});

$pm->start();

Error:

Fatal error: Swoole\Process\Pool::start(): require onMessage callback in @swoole-src/library/core/Process/Manager.php on line 57

You are just missing a listener for the messages, so the processes can communicate between each other by message-passing:

$pm->on('message', function (Pool $pool, string $data) {
});

This will retrun

Call to undefined method Swoole\Process\Manager::on()

I am using docker swoole : phpswoole/swoole:4.8-php8.0
