_DEBUG_RANGE是什么意思

[elated]

STL中好多的_DEBUG_RANGE是什么意思？

template<class _InIt, class _Ty>
inline
	_InIt _Find(_InIt _First, _InIt _Last, const _Ty& _Val)
	{	// find first matching _Val
	_DEBUG_RANGE(_First, _Last);
	for (; _First != _Last; ++_First)
		if (*_First == _Val)
			break;
	return (_First);
	}

#define _DEBUG_RANGE(first, last) \
_DEBUG_RANGE_IMPL(first, last, __FILEW__, __LINE__)

[jackyjkchen]

#define _DEBUG_RANGE_IMPL _Debug_range

template<class _InIt> inline
void __CLRCALL_OR_CDECL _Debug_range(_InIt _First, _InIt _Last, const wchar_t *_File, unsigned int _Line)
{ // test iterator pair for valid range
_Debug_range2(_First, _Last, _File, _Line, _Iter_cat(_First));
}

[jackyjkchen]

// TEMPLATE FUNCTION _Debug_range
template<class _InIt> inline
void __CLRCALL_OR_CDECL _Debug_range2(_InIt, _InIt, const wchar_t *, unsigned int ,
input_iterator_tag)
{ // test iterator pair for valid range, arbitrary iterators
}
