# std::multimap::emplace_hint

From cppreference.com
< cpp‎ | container‎ | multimap

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

Inserts a new element to the container, using `hint` as a suggestion where the element should go. The element is constructed in-place, i.e. no copy or move operations are performed.

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 function, forwarded with std::forward<Args>(args)....

No iterators or references are invalidated.

### [edit] 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

### [edit] Return value

Returns an iterator to the newly inserted element.

### [edit] Complexity

Logarithmic in the size of the container in general, but amortized constant if the new element is inserted just before `hint`.
