Yes (as part of STL): section 25.2.2 Swap: template<class T> void swap(T& a, T& b); Requires: Type T is Assignable (23.1).

I don't know where you can read about this implementation, but you can read the implementation itself (there isn't much to it :) // gcc-3.4.3/include/c++/3.4.3/bits/stl_algobase.h /** * @brief Swaps two values. * @param a A thing of arbitrary type. * @param b Another thing of arbitrary type. * @return Nothing. * * This is the simple classic generic implementation. It will work on * any type which has a copy constructor and an assignment operator. */ template<typename _Tp> inline void swap(_Tp& __a, _Tp& __b) { // concept requirements __glibcxx_function_requires(_SGIAssignableConcept<_Tp>) const _Tp __tmp = __a; __a = __b; __b = __tmp; } Cheers, -- In order to understand recursion you must first understand recursion.
