std::unorde...emplace_hint(3) C++ Standard Libarystd::unorde...emplace_hint(3)

NAME
       std::unordered_multimap::emplace_hint   -  std::unordered_multimap::em-
       place_hint

Synopsis
	  template<		  class...		 Args		     >
       (since C++11)
	  iterator emplace_hint( const_iterator	hint, Args&&...	args );

	  Inserts a new	element	into the container, using hint as a suggestion
       where the
	  element should go.

	  The	constructor   of   the	element	 type  (value_type,  that  is,
       std::pair<const Key, T>)
	  is called with exactly the same arguments as supplied	to  the	 func-
       tion, forwarded
	  with std::forward<Args>(args)....

	  If  after  the  operation the	new number of elements is greater than
       old
	  max_load_factor() * bucket_count() a rehashing takes place.
	  If rehashing occurs (due to the insertion), all iterators are	inval-
       idated. Otherwise
	  (no rehashing), iterators are	not invalidated.

Parameters
	  hint - iterator, used	as a suggestion	as to where to insert the  new
       element
	  args - arguments to forward to the constructor of the	element

Return value
	  An iterator to the inserted element.

Exceptions
	  If  an  exception is thrown for any reason, this function has	no ef-
       fect (strong
	  exception safety guarantee).

Complexity
	  Amortized constant on	average, worst case linear in the size of  the
       container.

	   This	section	is incomplete
