<p>The <code>pthread_cancel()</code> function will request that thread be canceled.

The target thread's cancelability state, enabled, or disabled, determines when the cancellation takes effect: When the cancellation is acted on, thread will be terminated.

the target thread until the thread changes the cancelability or
