std::barrie...ive_and_wait(3) C++ Standard Libary std::barrie...ive_and_wait(3) NAME std::barrier::arrive_and_wait - std::barrier::arrive_and_wait Synopsis void arrive_and_wait(); (since C++20) Atomically decrements the expected count by 1, then blocks at the syn- chronization point for the current phase until the phase completion step of the cur- rent phase is run. Equivalent to wait(arrive());. The behavior is undefined if the expected count for the current phase is zero. Parameters (none) Return value (none) Exceptions Throws std::system_error with an error code allowed for mutex types on error. Notes If the current expected count is decremented to zero in the call to this function, the phase completion step is run and this function does not block. If the current expected count is zero before calling this function, the initial expected count for all subsequent phases is also zero, which means the barrier cannot be reused.
