std::experi...ve_and_wait(3) C++ Standard Libary std::experi...ve_and_wait(3) NAME std::experimental::flex_barrier::arrive_and_wait - std::experimen- tal::flex_barrier::arrive_and_wait Synopsis void arrive_and_wait(); (concurrency TS) Blocks and arrives at the flex_barrier's synchronization point. The behavior is undefined if the calling thread is not in the set of participating threads of this flex_barrier. Calls to arrive_and_wait synchronizes with the start of the comple- tion phase of the flex_barrier. The completion of the completion phase synchronizes with the return from the call. Calls to arrive_and_drop and arrive_and_wait never introduce data races with themselves or each other. Notes It is safe for a thread to call either arrive_and_wait() or ar- rive_and_drop() immediately on return from this call (provided that the function ob- ject for the completion phase did not return zero). It's not necessary to ensure that all blocked threads have exited arrive_and_wait() before a thread calls it again. The completion phase executes the function object specified when the flex_barrier was constructed. If it returns -1, the set of participating threads is unchanged; otherwise, the set of participating threads is a new set with the size equal to the return value N, and consists of the next N threads to arrive at the synchronization point. If N == 0, the flex_barrier can only be destroyed. The initial set of participating threads for a flex_barrier con- structed for num_threads threads is the first num_threads to arrive at its syn- chronization point. Exceptions Throws nothing.
