std::forward_list::insert_after

From cppreference.com
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()
