explicit barrier( std::ptrdiff_t num_threads );	(1)	(concurrency TS)
barrier( const barrier & ) = delete;	(2)	(concurrency TS)

1) Constructs a barrier for num_threads participating threads. The set of participating threads is the first num_threads threads to arrive at the synchronization point.

2) Copy constructor is deleted; barrier is not copyable.

Parameters

num_threads

-

the number of participating threads for the barrier; must be non-negative

Notes

If num_threads is zero, the set of participating threads is empty, and barrier can only be destroyed.
