REGISTER_NETDEVICE_N(9) Network device support REGISTER_NETDEVICE_N(9)NAME
register_netdevice_notifier - register a network notifier block
int register_netdevice_notifier(struct notifier_block * nb);
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

Tk_HandleEvent - invoke event handlers for window system events
XEvent *eventPtr (in) Pointer to X event to dispatch to relevant handler(s). It is important that all unused fields of the struc-
ture be set to zero.
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.
