std::barrier::arrive(3) C++ Standard Libary std::barrier::arrive(3) NAME std::barrier::arrive - std::barrier::arrive Synopsis [[nodiscard]] arrival_token arrive( std::ptrdiff_t n = 1 ); (since C++20) Constructs an arrival_token object associated with the phase synchro- nization point for the current phase. Then, decrements the expected count by n. This function executes atomically. The call to this function strongly happens-before the start of the phase completion step for the current phase. The behavior is undefined if n is less than or equal to 0 or greater than the expected count for the current barrier phase. Parameters n - the value by which the expected count is decreased Return value The constructed arrival_token object. Exceptions Throws std::system_error with an error code allowed for mutex types on error. Notes This function can cause the completion step for the current phase to start.
