std::multiset::insert(3)       C++ Standard Libary	std::multiset::insert(3)

NAME
     std::multiset::insert - std::multiset::insert

Synopsis
	iterator insert( const value_type& value );	     (1)
	iterator insert( value_type&& value );		     (2) (since C++11)
	iterator      insert(	   iterator	 pos,	   const     value_type&
     (until C++11)
	value );
	iterator	insert(        const_iterator	      pos,	   const
     (since C++11)
	value_type& value );
	iterator    insert(    const_iterator	pos,   value_type&&	     (4)
     (since C++11)
	value );
	template< class InputIt >			     (3) (5)
	void insert( InputIt first, InputIt last );
	void	insert(    std::initializer_list<value_type>	ilist	     (6)
     (since C++11)
	);
	iterator    insert(    node_type&&   nh   );			     (7)
     (since C++17)
	iterator   insert(   const_iterator   pos,   node_type&&   nh	     (8)
     (since C++17)
	);

	Inserts element(s) into the container. The order of the remaining equiv-
     alent
	elements is preserved.

	1,2)  Inserts  value. If the container has elements with equivalent key,
     inserts at
	the upper bound of that range.
	3,4) Inserts value in the position as close as possible to the	position
     just prior
	to pos.
	5) Inserts elements from range [first, last).
	6) Inserts elements from initializer list ilist.
	7)  If	nh is an empty node handle, does nothing. Otherwise, inserts the
     element owned
	by nh into the container and returns an iterator  pointing  at	the  in-
     serted element.
	If  a  range containing elements with keys equivalent to nh.key() exists
     in the
	container, the element is inserted at the end of that range. The  behav-
     ior is
	undefined if nh is not empty and get_allocator() != nh.get_allocator().
	8) If nh is an empty node handle, does nothing and returns the end iter-
     ator.
	Otherwise,  inserts  the element owned by nh into the container, and re-
     turns the
	iterator pointing to the element with key equivalent  to  nh.key().  The
     element is
	inserted as close as possible to the position just prior to pos. The be-
     havior is
	undefined if nh is not empty and get_allocator() != nh.get_allocator().

	No iterators or references are invalidated.
	If  the  insertion is successful, pointers and references to the element
     obtained
	while it is held in the node handle are invalidated,  and  pointers  and
     references
	obtained to that element before it was extracted become valid.
	(since C++17)

Parameters
	pos	    - iterator to the position before which the new element will
     be inserted
	value	    - element value to insert
	first, last - range of elements to insert
	ilist	    - initializer list to insert the values from
	nh	    - a compatible node handle

Type requirements
	-
	InputIt must meet the requirements of LegacyInputIterator.

Return value
	1-4) An iterator to the inserted element.
	5,6) (none)
	7,8) End iterator if nh was empty, iterator pointing to the inserted el-
     ement
	otherwise.

Exceptions
	1-4,7,8)  If  an exception is thrown by any operation, the insertion has
     no effect.
	5,6) No exception safety guarantee.

Complexity
	1,2,7) O(log(size()))
	3,4,8) Amortized constant if the insertion happens in the position  just
     before pos,
	O(log(size())) otherwise.
	5,6) O(NA.log(size() + N)), where N is the number of elements to insert.
