Return a const iterator pair covering elements equivalent to key.

bsl::pair<unordered_multiset<KEY, HASH, EQUAL, ALLOCATOR>::const_iterator, unordered_multiset<KEY, HASH, EQUAL, ALLOCATOR>::const_iterator>
equal_range(key_type const& key) const;Return a pair of iterators providing non-modifiable access to the sequence of value_type objects in this unordered multiset equivalent to the specified key, where the first iterator is positioned at the start of the sequence, and the second is positioned one past the end of the sequence. If this unordered multiset contains no value_type objects equivalent to the key, then the two returned iterators will have the same value.
pair of const iterators delimiting the equal-key range
