unchecked_set_difference
Same as set_difference, but allows the use of an unchecked iterator as output iterator when _SECURE_SCL=1 is defined. unchecked_set_difference is defined in the stdext namespace.
注意
This algorithm is a Microsoft extension to the Standard C++ Library. Code implemented using this algorithm will not be portable.
template<class InputIterator1, class InputIterator2, class OutputIterator>
OutputIterator unchecked_set_difference(
InputIterator1_First1,
InputIterator1_Last1,
InputIterator2_First2,
InputIterator2_Last2,
OutputIterator_Result
);
template<class InputIterator1, class InputIterator2, class OutputIterator, class BinaryPredicate>
OutputIterator unchecked_set_difference(
InputIterator1 _First1,
InputIterator1_Last1,
InputIterator2_First2,
InputIterator2_Last2,
OutputIterator_Result,
BinaryPredicate_Comp
);
Parameters
_First1
An input iterator addressing the position of the first element in the first of two sorted source ranges to be united and sorted into a single range representing the difference of the two source ranges._Last1
An input iterator addressing the position one past the last element in the first of two sorted source ranges to be united and sorted into a single range representing the difference of the two source ranges._First2
An input iterator addressing the position of the first element in second of two consecutive sorted source ranges to be united and sorted into a single range representing the difference of the two source ranges._Last2
An input iterator addressing the position one past the last element in second of two consecutive sorted source ranges to be united and sorted into a single range representing the difference of the two source ranges._Result
An output iterator addressing the position of the first element in the destination range where the two source ranges are to be united into a single sorted range representing the difference of the two source ranges._Comp
User-defined predicate function object that defines the sense in which one element is greater than another. The binary predicate takes two arguments and should return true when the first element is less than the second element and false otherwise.
Return Value
An output iterator addressing the position one past the last element in the sorted destination range representing the difference of the two source ranges.
Remarks
See set_difference for a code sample.
