std::experimental::barrier(3) C++ Standard Libary std::experimental::barrier(3) NAME std::experimental::barrier - std::experimental::barrier Synopsis Defined in header <experimental/barrier> class barrier; (concurrency TS) The class std::experimental::barrier provides a thread-coordination mechanism that allows a set of participating threads to block until an operation is completed. Unlike std::experimental::latch, barriers are reusable; once the partic- ipating threads are released from a barrier's synchronization point, they can reuse the same barrier. A barrier has a completion phase, which is executed by one of the par- ticipating threads once all threads in the set of participating threads arrive at the synchronization point. The arrive_and_wait and arrive_and_drop calls synchronize with the start of the completion phase; the end of the completion phase synchronizes with the returns from all calls blocked by its completion. For std::experimental::barrier, the completion phase is empty. std::experimental::flex_barrier allows the user to control the comple- tion phase with a function object. The set of participating threads for a barrier constructed for num_threads threads is the first num_threads threads to arrive at its synchronization point after construction. The same set of threads (except for threads that called arrive_and_drop()) must arrive at the barrier each cycle. Member functions constructor constructs a barrier (public member function) destructor destroys the barrier (public member function) operator= not copy-assignable [deleted] (public member function) arrive_and_wait arrive at the synchronization point and block (public member function) arrive at the synchronization point and remove the cur- rent thread arrive_and_drop from the set of participating threads (public member function) http://cppreference.com 2024.06.10 std::experimental::barrier(3)
