20 Whenever possible wxWidgets provides an efficient, CPU-specific,
21 implementation of this function. If such implementation is available, the
22 symbol wxHAS_ATOMIC_OPS is defined. Otherwise this function still exists
23 but is implemented in a generic way using a critical section which can be
24 prohibitively expensive for use in performance-sensitive code.
