# std::forward_list::insert_after

From cppreference.com
< cpp‎ | container‎ | forward list

iterator insert_after( const_iterator pos, const T& value ); | (1) | (since C++11)
iterator insert_after( const_iterator pos, T&& value ); | (2) | (since C++11)
iterator insert_after( const_iterator pos, size_type count, const T& value ); | (3) | (since C++11)
template< class InputIt > iterator insert_after( const_iterator pos, InputIt first, InputIt last ); | (4) | (since C++11)
iterator insert_after( const_iterator pos, std::initializer_list<T> ilist ); | (5) | (since C++11)

Inserts elements after the specified position in the container.

1-2) inserts `value` after the element pointed to by `pos`
3) inserts `count` copies of the `value` after the element pointed to by `pos`
4) inserts elements from range `[first, last)` after the element pointed to by `pos`. The behavior is undefined if `first` and `last` are iterators into *this.
5) inserts elements from initializer list `ilist`.

No iterators or references are invalidated.

### [edit] Parameters

pos | - | element after which the content will be inserted
value | - | element value to insert
first, last | - | the range of elements to insert
ilist | - | initializer list to insert the values from
Type requirements
- `InputIt` must meet the requirements of `InputIterator`.

### [edit] Return value

1-2) Iterator to the inserted element.
3) Iterator to the last element inserted, or `pos` if count==0.
4) Iterator to the last element inserted, or `pos` if first==last.
5) Iterator to the last element inserted, or `pos` if `ilist` is empty.

### [edit] Exceptions

If an exception is thrown during `insert_after` there are no effects (strong exception guarantee).

### [edit] Complexity

1-2) Constant.
3) Linear in count
4) Linear in std::distance(first, last)
5) Linear in ilist.size()
