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

    Your symbiont must call SMB$INITIALIZE before calling any
    other SMB routines. It calls SMB$INITIALIZE in order to do the
    following:

    o  Allocate and initialize the SMB facility's internal database.

    o  Establish the interface between the job controller and the
       symbiont.

    o  Determine the threading scheme of the symbiont.

    o  Set up the mechanism to wake your symbiont when a message is
       received.

    After the symbiont calls SMB$INITIALIZE, it can communicate with
    the job controller using the other SMB routines.
