NAME
     quntimeout - cancel previous qtimeout function call

SYNOPSIS
     #include 
     #include 



     clockt quntimeout(queuet *q, timeoutidt id);


INTERFACE LEVEL
     Solaris DI specific (Solaris DI).

PARAMETERS
     q     Pointer to a STREAMS queue structure.


     id    Opaque timeout ID a previous qtimeout(9F) call.


DESCRIPTION
     The quntimeout() function  cancels  a  pending  qtimeout(9F)
     request.  The  quntimeout()  function is tailored to be used
     with the enhanced  STREAMS  framework  interface,  which  is
     based  on  the  concept of perimeters. (See mt-streams(9F).)
     quntimeout() returns when the timeout has been cancelled  or
     finished executing. The timeout will be cancelled even if it
     is blocked at the perimeters associated with the queue. qun-
     timeout()  should  be  executed for all outstanding timeouts
     before a driver or module  close  returns.  All  outstanding
     timeouts  and  bufcalls  must  be  cancelled before a driver
     close routine can block and before the close  routine  calls
     qprocsoff(9F).

RETURN VALUES
     The quntimeout() function returns -1 if the id is not found.
     Otherwise, quntimeout() returns a 0 or positive value.

CONTEXT
     The quntimeout() function can be called  from  user,  inter-
     rupt, or kernel context.
