# unregister\_netdevice\_notifier(9)

unregister a network notifier block

## NAME

unregister\_netdevice\_notifier - unregister a network notifier block

## SYNOPSIS

**int unregister\_netdevice\_notifier(struct notifier\_block \*** *nb***);**

## ARGUMENTS

*nb*

notifier

## DESCRIPTION

Unregister a notifier previously registered by **register\_netdevice\_notifier**. The notifier is unlinked into the kernel structures and may then be reused. A negative errno code is returned on a failure.

After unregistering unregister and down device events are synthesized for all devices on the device list to the removed notifier to remove the need for special case cleanup code.
