Traditionally, C and C++ have a long tradition of portable code for system programming. The atomic feature that was introduced in the C++11 standard reinforces this by adding, natively, the guarantee that an operation is seen as atomic by other threads.

Any operation that's performed on the atomic variable is now protected from other threads.
