“pseudo-atomic” operations in C++

Question

So I\'m aware that nothing is atomic in C++. But I\'m trying to figure out if there are any \"pseudo-atomic\" assumptions I can make. The reason is that I want to avoid using

Answer 1

If your C++ implementation supplies the library of atomic operations specified by n2145 or some variant thereof, you can presumably rely on it. Otherwise, you cannot in general rely on "anything" about atomicity at the language level, since multitasking of any kind (and therefore atomicity, which deals with multitasking) is not specified by the existing C++ standard.
