if_detach(9r)
NAME
  if_detach - Network: Removes an interface from the list of active
  interfaces

SYNOPSIS
  int if_detach(
	  struct ifnet *ifp );

ARGUMENTS
  *ifp
      Specifies a pointer to an ifnet data structure.

DESCRIPTION
  The if_detach() routine removes an interface from the list of active
  interfaces if it believes there are no more users of the interface.  It
  makes this determination based upon whether or not there are any interface
  addresses still in use.

NOTES
  Even after if_detach() decides to remove the interface from the list of
  active interfaces, it still cannot know for certain whether or not there
  are still users of the interface. So, to prevent undesirable calls to the
  network driver from happening after the device has been removed from the
  active interface list, if_detach() replaces the function pointers (for
  example, if_start, if_ioctl) in the ifnet data structure with pointers to
  harmless routines.

RETURN VALUES
  EBUSY
      The device is still in use.

  ENODEV
      The specified device was not found in the list of active interfaces.

  ESUCCESS
      The device was successfully detached.
