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 = std::memory_order_seq_cst ) volatile (1) (since C++11) 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 re- turns the value it held before. Parameters order - the memory synchronization order 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 constraints for the given (C++11) atomic operation (enum) http://cppreference.com 2024.06.10 std::atomic...est_and_set(3)
