<?php

declare(strict_types=1);

require __DIR__ . '/vendor/autoload.php';

use Io\Poll\Context;
use Io\Poll\Event;
use Io\Poll\StreamPollHandle;

$context = new Context();
$stream = fopen('php://temp', 'r+');
fwrite($stream, "hello\n");
rewind($stream);

$watcher = $context->add(new StreamPollHandle($stream), [Event::Read], 'demo');
$ready = $context->wait(0, 1000);

foreach ($ready as $triggered) {
    var_dump($triggered->getData(), $triggered->getTriggeredEvents());
}
