Clang allows the C keyword _Atomic in C++. That's not part of the C++ standard either > What prevent stdatomic.h to detect if it is included in C++ mode and > includes C++ <atomic> instead? Even if it did that, it wouldn't guarantee that C's atomic_int and C++'s std::atomic_int are compatible. So you'd still need to rely on non-portable implementation-specific assumptions.
