qunbufcall(9f)

qunbufcall(9F)                 Kernel Functions                 qunbufcall(9F)



NAME
       qunbufcall - cancel a pending qbufcall request

SYNOPSIS
       #include <sys/stream.h>
       #include <sys/ddi.h>

       void qunbufcall(queue_t *q, bufcall_id_t id);

INTERFACE LEVEL
       Solaris DDI specific (Solaris DDI).

PARAMETERS
       q     Pointer to STREAMS queue_t structure.


       id    Identifier returned from qbufcall(9F).


DESCRIPTION
       The  qunbufcall()  function  cancels  a pending qbufcall() request. The
       argument id is a non-zero identifier of the request to be cancelled. id
       is  returned  from  the  qbufcall()  function  used to issue the cancel
       request.


       The qunbufcall() function is tailored to  be  used  with  the  enhanced
       STREAMS  framework  interface  which is based on the concept of perime‐
       ters. (See mt-streams(9F).) qunbufcall() returns when the  bufcall  has
       been  cancelled  or  finished  executing. The bufcall will be cancelled
       even if it is blocked at the perimeters associated with the queue.  All
       outstanding  timeouts  and  bufcalls  must be cancelled before a driver
       close routine can block and  before  the  close  routine  calls  qproc‐
       soff(9F).

CONTEXT
       The qunbufcall() function can be called from user, interrupt, or kernel
       context.
