- Is there a difference between the _Atomic type qualifier and type . . .
Atomic type specifiers :-:) Syntax: _Atomic ( type-name ); You can declare an atomic integer like this: _Atomic(int) counter; The _Atomic keyword can be used in the form _Atomic(T), where T is a type, as a type specifier equivalent to _Atomic T Thus, _Atomic(T) x, y; declares x and y with the same type, even if T is a pointer type This allows for trivial C++0x compatibility with a C++ only

- When should you use std::atomic instead of std::mutex?
When is_lock_free returns false, it means that atomic has a lock, and equivalent performance with code with locks This does not mean that you should always use atomic instead of mutex-based approach, conversely, if you expect is_lock_free to be always false, you should not use atomic: Use of atomic for such cases would be misleading first of all
