# register\_netdevice\_notifier(9)

register a network notifier block

## NAME

register\_netdevice\_notifier - register a network notifier block

## SYNOPSIS

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

## ARGUMENTS

## 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.
