* @brief Support for atomic operations.
*
* Atomic operations can be used to implement low-level synchronization
* primitives on SMP systems, like spin locks. All atomic operations are
* defined in terms of C11 (ISO/IEC 9899:2011) or C++11 (ISO/IEC 14882:2011).
* For documentation use the standard documents.
