     *      of this is in the shared data segment of
     *      XWPHOOK.DLL, and a pointer to that structure
     *      is returned to the daemon which initially loads
     *      that DLL by hookInit and then stored by the
     *      daemon. As a result, this structure is shared
     *      between the hook and the daemon, and both can
     *      access it at any time.
     *
     *      This is statically initialized to 0 when the hook
     *      DLL is loaded. hookInit will then set up most
     *      fields in here.
     *
     *      This contains setup data (the state of the
     *      hook), some data which needs to be cached,
     *      as well as the HOOKCONFIG structure which
     *      is used to configure the hook and the daemon.
     *      That sub-structure gets (re)loaded from OS2.INI
     *      upon daemon startup and when XDM_HOOKCONFIG is
     *      received by fnwpDaemonObject.
