   5 NAME
   6        free_rtn - structure that specifies a driver's message-freeing routine
   7 
   8 SYNOPSIS
   9        #include <sys/stream.h>
  10 
  11 
  12 INTERFACE LEVEL
  13        Architecture independent level 1 (DDI/DKI).
  14 
  15 DESCRIPTION
  16        The  free_rtn structure is referenced by the  datab structure. When
  17        freeb(9F) is called to free the message, the driver's message-freeing
  18        routine (referenced through the  free_rtn structure) is called, with
  19        arguments, to free the data buffer.
  20 
  21 STRUCTURE MEMBERS
  22          void     (*free_func)()      /* user's freeing routine */
  23          char     *free_arg           /* arguments to free_func() */
  24 
  25 
  26 
  27        The  free_rtn structure is defined as type  frtn_t.
