iterator insert( const_iterator pos, std::initializer_list<T> ilist );
(5) (since C++11)

Inserts elements at specified location in the container.

1-2) inserts value before the location pointed to by pos
3) inserts count copies of the value before the location pointed to by pos
4) inserts elements from range [first, last) before the location 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.

Contents

[edit] Parameters

pos - iterator to the location before which the content will be inserted. pos may be the end() iterator
value - element value to insert
first, last - the range of elements to insert, can't be iterators into container for which insert is called
ilist - initializer list to insert the values from
Type requirements
-
InputIt must meet the requirements of InputIterator.

[edit] Return value

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

[edit] Complexity

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