-    template<class T>
-    T atomic_exchange(T* const ptr_to_value, const T new_value);
+   Atomically executes ``old_value = *ptr_to_value; *ptr_to_value = new_value; return old_value;``,
+   where ``old_value`` is the value at address ``ptr_to_value`` before doing the exchange.
 
-  Atomically executes ``old_value = *ptr_to_value; *ptr_to_value = new_value; return old_value;``. 
+   :param ptr_to_value: address of the value to be updated
 
-  - ``ptr_to_value``: address of the to be updated value.
-  - ``new_value``: new value.
-  - ``old_value``: value at address ``ptr_to_value`` before doing the exchange.
