REGISTER_NETDEVICE_N(9) 				      Network device support					   REGISTER_NETDEVICE_N(9)

NAME

       register_netdevice_notifier - register a network notifier block

SYNOPSIS

       int register_netdevice_notifier(struct notifier_block * nb);

ARGUMENTS

       nb
	   notifier

DESCRIPTION

       Register a notifier to be called when network device events occur. The notifier passed is linked into the kernel structures and must not be
       reused until it has been unregistered. A negative errno code is returned on a failure.

       When registered all registration and up events are replayed to the new notifier to allow device to have a race free view of the network
       device list.

DESCRIPTION

       Tk_HandleEvent is a lower-level	procedure  that  deals	with  window  events.	It  is	called	by  Tcl_ServiceEvent  (and  indirectly	by
       Tcl_DoOneEvent),  and  in a few other cases within Tk.  It makes callbacks to any window event handlers (created by calls to Tk_CreateEven-
       tHandler) that match eventPtr and then returns.	In some cases it may be useful for an application to bypass the Tk event  queue  and  call
       Tk_HandleEvent directly instead of calling Tcl_QueueEvent followed by Tcl_ServiceEvent.

       This  procedure	may  be  invoked  recursively.	 For example, it is possible to invoke Tk_HandleEvent recursively from a handler called by
       Tk_HandleEvent.	This sort of operation is useful in some modal situations, such as when a notifier has been popped up and  an  application
       wishes to wait for the user to click a button in the notifier before doing anything else.
