Signals that the calling thread has arrived at the synchronization point and block until all the participating threads have arrived.
void arrive_and_wait();
Either the calling thread is one of the first N
threads to arrive at *this since construction, where
N is the value of the num_threads
parameter to the constructor, or the calling thread is already
one of the set of participating threads for *this.
Signal that the calling thread has arrived at the flex_barrier. If this is the
last of the participating threads to arrive then the completion function (if any) is called on
one of the participating threads, and then all threads blocked
on *this
are unblocked and the flex_barrier
is reset, otherwise blocks until all the participating threads
have arrived.
Nothing.
