Multiset is an associative container that contains a sorted set of objects of type Key. Unlike set, multiple keys with equal values are allowed. Sorting is done using the key comparison function Compare. Search, insertion, and removal operations have logarithmic complexity.

The order of the elements that compare equivalent is the order of insertion and does not change. (since C++11)

std::multiset meets the requirements of Template:concept, Template:concept, Template:concept and Template:concept.

Notes

The member types iterator and const_iterator may be aliases to the same type. This means defining a pair of function overloads using the two types as parameter types may violate the One Definition Rule. Since iterator is convertible to const_iterator, a single function with a const_iterator as parameter type will work instead.
