# std::experimental::barrier::barrier

From cppreference.com
< cpp‎ | experimental‎ | barrier

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.

### [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.
