##### basic_system_executor::query (1 of 3 overloads)

Query the current value of the `allocator` property.

    template<
        typename OtherAllocator>
    constexpr Allocator query(
        execution::allocator_t< OtherAllocator > ) const;

Do not call this function directly. It is intended for use with the `query` customisation point.

For example:

    asio::system_executor ex;
    auto alloc = asio::query(ex,
        asio::execution::allocator);
