NAME    [Toc]    [Back]

       unbufcall - STREAMS: Cancels a pending bufcall request

SYNOPSIS    [Toc]    [Back]

       #include <sys/stream.h>

       void unbufcall(
               int id );

ARGUMENTS    [Toc]    [Back]

       Specifies  a nonzero identifier for the request to be canceled.
  This nonzero identifier is returned to the  module
       from a previous call to the bufcall interface.

DESCRIPTION    [Toc]    [Back]

       The unbufcall interface cancels a pending bufcall request.
       The id argument is a nonzero identifier for the request to
       be  canceled.  This  nonzero identifier is returned to the
       module from a previous call to the bufcall interface.

       The unbufcall interface will not return until the  pending
       callback  is  canceled  or has run. Because of this, locks
       acquired by the callback  interface  should  not  be  held
       across  the  call to unbufcall or a deadlock condition can
       occur.

RETURN VALUES    [Toc]    [Back]

       None
