+    This function increments @a value in an atomic manner.
+
+    @note It is recommended to use @c std::atomic instead of this function in
+    any new code.
+
+    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.
+
+    Returns the new value after the increment (the return value is only
+    available since wxWidgets 3.1.7, this function doesn't return anything in
+    previous versions of the library).
