27 * @brief Support for atomic operations.
28 *
29 * Atomic operations can be used to implement low-level synchronization
30 * primitives on SMP systems, like spin locks.  All atomic operations are
31 * defined in terms of C11 (ISO/IEC 9899:2011) or C++11 (ISO/IEC 14882:2011).
32 * For documentation use the standard documents.
