To globally replicate and populate bulk data functions:

Files: Stl_uninitialized.h Analyze one of the many functions: the Uninitialized_copy function. There are three versions of this function: a template function, a char type overload, and a WCHAR type overload. Please see for details. Char type overloading: inline char* uninitialized_copy (const char* __first, const char* __last,char* __result) {memmove (__result, __fi  RST, __last-__first); return __result + (__last-__first);} WCHAR type overloading: inline wchar_t* uninitialized_copy (const wchar_t* __first, const wchar_t* __last,wchar_t* __result) {memmove (  __result, __first, sizeof (wchar_t) * (__last-__first)); return __result + (__last-__first);} Template type: Using the Type feature extraction template <class _inputiter, class _forwarditer>inline _forwarditer uninitialized_copy (_inputiter __first, _inputiter __last, _forwarditer __result) {return __uninitialized_copy (__first, __last, __result,__VALUE_TYPE (__result));} Template <class _inputiter, class _forwarditer, Class _tp>inline _forwarditer__uninitialized_copy (_InputIter __  First, _inputiter __last,_forwarditer __result, _tp*) {typedef typename __type_traits<_tp>::is_pod_type _Is_POD; Return __uninitialized_copy_aux (__first, __last, __result, _is_pod ());} Template <class _inputiter, class _forwarditer>inline _forwarditer __uninitialized_copy_aux (_InputIter __first, _inputiter __last,_forwarditer __result,__true_type) {return copy (__first, __last, __result);} Template <class _inputiter, class _forwarditer>_forwarditer __uninitialized_copy_aux (_inputiter __first, _ Inputiter __last, _forwarditer __result, __false_type) {_forwarditer __CU  R = __result;    __stl_try {for (; __first! = __last; ++__first, ++__cur) _construct (&*__cur, *__first);  return __cur; } __stl_unwind (_destroy (__result, __cur));}
