NAME
       unbufcall - STREAMS: Cancels a pending bufcall request

SYNOPSIS
       #include <sys/stream.h>

       void unbufcall(
	       int id );

ARGUMENTS
       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
       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
       None
