# atomic_ref
Header-only implementation of [std::atomic_ref][1] for C++14.
Currently supports Microsoft Visual Studio on x86 and amd64,
and GCC/clang with support for __atomic builtins.
[1]: https://en.cppreference.com/w/cpp/atomic/atomic_ref
## Getting started
Place the library anywhere and add the `include` directory to your
project's include paths.
Bring `avakar::atomic_ref` to your namespace and enjoy.
#include
using avakar::atomic_ref;
## License
The software is distributed under the terms of the MIT license.
## Lock- and wait-freeness
The standard mandates a constexpr bool member called `is_always_lock_free`.
This implementation also defines a bool constexpr member `is_always_wait_free`.
Note that in particular, operations on `uint64_t` in Intel's 32-bit platforms
are not wait free.
## Safe variant
The library also defines the class `avakar::safe_atomic_ref`,
which forces you to use the more verbose function calls insted of operators.
In particual, `safe_atomic_ref` doesn't provide
* implicit conversion operator (`operator T`),
* pre- and post-increment,
* pre- and post-decrement,
* the assignment operator, or
* any of the compound assignment operators.
