unchecked_set_union

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Same as set_union, but allows the use of an unchecked iterator as output iterator when _SECURE_SCL=1 is defined. unchecked_set_union is defined in the stdext namespace.

Note Note

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_union(
      InputIterator1_First1,
      InputIterator1_Last1,
      InputIterator2_First2,
      InputIterator2_Last2,
      OutputIterator_Result
   );
template<class InputIterator1, class InputIterator2, class OutputIterator, class BinaryPredicate>
   OutputIterator unchecked_set_union(
      InputIterator1 _First1,

   );

_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 union 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 union 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 union 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 union 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 union 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.

An output iterator addressing the position one past the last element in the sorted destination range representing the union of the two source ranges.

See set_union for a code sample.
