VMS Help SMB Routines  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The Symbiont/Job Controller Interface (SMB) routines provide the
    interface between the job controller and symbiont processes. A
    user-written symbiont must use these routines to communicate with
    the job controller.

  Additional Information (explode) :

• SMB$CHECK_FOR_MESSAGE
• SMB$INITIALIZE
• SMB$READ_MESSAGE
• SMB$READ_MESSAGE_ITEM
• SMB$SEND_TO_JOBCTL
