# Flock. Simple locking mechanism on top of flock()

## Usage

```php

$file = '/tmp/my_lock.pid';

$lock = new F3\Flock\Lock($file);

// Non-blocking case. Acquire lock if it's free, otherwse exit immediately

if ($lock->acquire()) {

    // only one instance can reach here

    ...

    // do some job

    ...

    $lock->release();

} else {

    die('Another process is running')

}

// Waiting case. Acquire lock if it's free, otherwse block until it's free and then acquire

if ($lock->acquire(F3\Flock\Lock::BLOCKING)) {

    // only one instance can reach here

    ...

    // do some job

    ...

    $lock->release();

} else {

    // We sould not get to this point in this case

}
