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.
