Whenever possible wxWidgets provides an efficient, CPU-specific,

implementation of this function. If such implementation is available, the

symbol wxHAS_ATOMIC_OPS is defined. Otherwise this function still exists
|

but is implemented in a generic way using a critical section which can be

prohibitively expensive for use in performance-sensitive code.
