   8 [section:ObjectHandleService Object handle service requirements]
   9
  10 An object handle service must meet the requirements for a [link
  11 boost_asio.reference.HandleService handle service], as well as the additional
  12 requirements listed below.
  13
  14 In the table below, `X` denotes an object handle service class, `a` denotes a
  15 value of type `X`, `b` denotes a value of type `X::implementation_type`, `ec`
  16 denotes a value of type `error_code`, and `wh` denotes a value meeting [link
  17 boost_asio.reference.WaitHandler `WaitHandler`] requirements.

  37       Initiates an asynchronous operation to wait for the object represented by
  38       handle `b` to become signalled. The operation is performed via the
  39       `io_service` object `a.get_io_service()` and behaves according to [link

  41       requirements.
