The signal is asynchronously directed to thread. - *thread_id* can be read from the :attr:`~threading.Thread.ident` attribute - of :attr:`threading.Thread`. For example, - ``threading.current_thread().ident`` gives the identifier of the current - thread. + Use :func:`threading.get_ident()` or the :attr:`~threading.Thread.ident` + attribute of :attr:`threading.Thread` to get a 'thread identifier' for + *thread_id*. If *signum* is 0, then no signal is sent, but error checking is still performed; this can be used to check if a thread is still running. |
