##### io_context::basic_executor_type::query (3 of 5 overloads)

Query the current value of the `relationship` property.

    constexpr execution::relationship_t query(
        execution::relationship_t ) const;

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

For example:

    auto ex = my_io_context.get_executor();
    if (asio::query(ex, asio::execution::relationship)
          == asio::execution::relationship.continuation)
      ...
