std::atomic...est_and_set(3) C++ Standard Libary std::atomic...est_and_set(3) NAME std::atomic_flag::test_and_set - std::atomic_flag::test_and_set Synopsis Defined in header <atomic> bool test_and_set(std::memory_order order = (1) (since C++11) std::memory_order_seq_cst) volatile noexcept; bool test_and_set(std::memory_order order = (2) (since C++11) std::memory_order_seq_cst) noexcept; Atomically changes the state of a std::atomic_flag to set (true) and returns the value it held before. Parameters order - the memory synchronization ordering for this operation See also clear atomically sets flag to false (public member function) atomic_flag_test_and_set atomically sets the flag to true and returns its atomic_flag_test_and_set_explicit previous value (C++11) (function) (C++11) memory_order defines memory ordering con- straints for the given (C++11) atomic operation (enum) http://cppreference.com 2022.07.31 std::atomic...est_and_set(3)
