unbufcall(9r)
NAME
  unbufcall - STREAMS: Cancels a pending bufcall request

SYNOPSIS
  #include <sys/stream.h>

  void unbufcall(
	  int id );

ARGUMENTS
  id  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
