Data Structures for Drivers                         streamtab(9S)



NAME
     streamtab - STREAMS entity declaration structure

SYNOPSIS
     #include 


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

DESCRIPTION
     Each STREAMS driver or module must have a  streamtab  struc-
     ture.


     streamtab is made up of qinit structures for both  the  read
     and  write  queue  portions of each module or driver. Multi-
     plexing drivers require both upper and  lower  qinit  struc-
     tures. The qinit structure contains the entry points through
     which the module or driver routines are called.


     Normally, the read QUEUE contains the open  and  close  rou-
     tines.  Both  the  read  and write queue can contain put and
     service procedures.

STRUCTURE MEMBERS
       struct qinit    *strdinit;    /* read QUEUE */
       struct qinit    *stwrinit;    /* write QUEUE */
       struct qinit    *stmuxrinit;  /* lower read QUEUE*/
       struct qinit    *stmuxwinit;  /* lower write QUEUE*/
