:mrdocs:

Deduce the template parameters `KEY` and `VALUE` from the `value_type` of the iterators supplied to the constructor of `unordered_multimap`. Deduce the template parameter `ALLOCATOR` from the other parameter passed to the constructor of `unordered_multimap`. This deduction guide does not participate unless the supplied allocator meets the requirements of a standard allocator.

Declared in `<bslstl_unorderedmultimap.h>`
