(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.[edit] Parameters
| num_threads | - | the number of participating threads for the barrier; must be non-negative |
[edit] Notes
If num_threads is zero, the set of participating threads is empty, and barrier can only be destroyed.
