##### io_context::basic_executor_type::query (2 of 5 overloads)

Query the current value of the `blocking` property.

    constexpr execution::blocking_t query(
        execution::blocking_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::blocking)
          == asio::execution::blocking.always)
      ...
