std::atomic...is_lock_free(3) C++ Standard Libary std::atomic...is_lock_free(3) NAME std::atomic_ref::is_lock_free - std::atomic_ref::is_lock_free Synopsis bool is_lock_free() const noexcept; (since C++20) Checks whether the atomic operations on this object are lock-free. Parameters (none) Return value true if the atomic operations on this object are lock-free, false other- wise. Notes All atomic types except for std::atomic_flag may be implemented using mutexes or other locking operations, rather than using the lock-free atomic CPU in- structions. Atomic types are also allowed to be sometimes lock-free, e.g. if only aligned memory accesses are naturally atomic on a given architecture, misaligned ob- jects of the same type have to use locks. The C++ standard recommends (but does not require) that lock-free atomic operations are also address-free, that is, suitable for communication between processes using shared memory. Example This section is incomplete Reason: no example See also is_always_lock_free indicates that the type is always lock-free [static] (public static member constant) Category: * Todo no example http://cppreference.com 2024.06.10 std::atomic...is_lock_free(3)
