NAME
     freertn - structure  that  specifies  a  driver's  message-
     freeing routine

SYNOPSIS
     #include 


INTERFACE LEVEL
     Architecture independent level 1 (DI/DKI).

DESCRIPTION
     The  freertn structure is referenced by the   datab  struc-
     ture.  When   freeb(9F)  is  called to free the message, the
     driver's message-freeing  routine  (referenced  through  the
     freertn  structure)  is called, with arguments, to free the
     data buffer.

STRUCTURE MEMBERS
       void     (*freefunc)()      /* user's freeing routine */
       char     *freearg           /* arguments to freefunc() */



     The  freertn structure is defined as type  frtnt.
