Since:
  OTP 21.0

  Request notification when more data is available to fetch using 
  erlang:dist_ctrl_get_data(DHandle) for the distribution channel
  identified by DHandle. When more data is present, the caller
  will be sent the message dist_data. Once a dist_data messages
  has been sent, no more dist_data messages will be sent until the 
  dist_ctrl_get_data_notification/1 function has been called again.

  Note:
    Only the process registered as distribution controller for the
    distribution channel identified by DHandle is allowed to
    call this function.

  This function is used when implementing an alternative
  distribution carrier using processes as distribution controllers. 
  DHandle is retrieved via the callback f_handshake_complete.
  More information can be found in the documentation of ERTS User's
  Guide ➜ How to implement an Alternative Carrier for the Erlang
  Distribution ➜ Distribution Module.
