pht\Vector::lock — Acquires the vector's mutex lock
Descripción
public pht\Vector::lock
(
) : void
This method will acquire the mutex lock associated with the vector. The mutex lock should always be acquired when manipulating the vector if it is being used by multiple threads.
The mutex locks of the Inter-Thread Communication (ITC) data structures are not reentrant. Attempting to reacquire an already-acquired mutex lock by the same thread will therefore cause a deadlock.

$vector->unlock();
}, $vector);
$thread->start();
// $vector is currently being used by multiple threads
$vector->lock();
$vector[] = 2;
$vector->unlock();
$thread->join();
