# std::multiset<Key,Compare,Allocator>::emplace_hint

< cpp‎ | container‎ | multiset

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

Inserts a new element to the container as close as possible to the position just before `hint`. The element is constructed in-place, i.e. no copy or move operations are performed.

The constructor of the element is called with exactly the same arguments as supplied to the function, forwarded with std::forward <Args>(args)....

No iterators or references are invalidated.

### Parameters

hint | - | iterator to the position before which the new element will be inserted
args | - | arguments to forward to the constructor of the element

### Return value

Returns an iterator to the newly inserted element.

### Exceptions

If an exception is thrown by any operation, this function has no effect (strong exception guarantee).

### Complexity

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