NAME

std::experimental::barrier::barrier - std::experimental::barrier::barrier

Synopsis

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.
