std::experi...ive_and_wait(3)  C++ Standard Libary std::experi...ive_and_wait(3)

NAME
     std::experimental::barrier::arrive_and_wait    -	 std::experimental::bar-
     rier::arrive_and_wait

Synopsis
	void arrive_and_wait();  (concurrency TS)

	Blocks and arrive at the barrier's synchronization point.

	The behavior is undefined if the calling thread is not	in  the  set  of
     participating
	threads of this barrier.

	Calls  to  arrive_and_wait synchronizes with the start of the completion
     phase of the
	barrier. The completion of the completion phase  synchronizes  with  the
     return from
	the call.

	Calls  to arrive_and_drop and arrive_and_wait never introduce data races
     with
	themselves or each other.

Notes
	It is safe  for  a  thread  to	call  either  arrive_and_wait()  or  ar-
     rive_and_drop()
	immediately  on return from this call. It's not necessary to ensure that
     all blocked
	threads have exited arrive_and_wait() before a thread calls it again.

	The  set  of  participating  threads  for  a  barrier  constructed   for
     num_threads threads
	is  the  first	num_threads to arrive at its synchronization point. This
     set does not
	change from cycle to cycle, except for threads removed from the set  due
     to
	arrive_and_drop() calls.

Exceptions
	Throws nothing.
