Overview

Lock (file lock), ripple provides a basic file lock, which is used in multiple processes to stagger the access time when seizing the same resource. The permissions of the lock are shared globally in the current process. You can use Lock as follows

example

$common = \Co\IO::Lock()->access('common');
$common->lock();

$task = \Co\System::Process()->task(function() use ($common){
    $common->lock();
    
    echo 'get lock success';
});

$runtime = $task->run();

\Co\delay(fn() => $common->unlock(),5);

$runtime->await();
