Overview

Package osnetconfig provides OS specific routines for detecting network changes and reading the route table; it uses cgo to to do so. Unfortunately some applications prefer to avoid the use of cgo entirely and this leads to a convoluted

Types

type IPRoute

type IPRoute struct {
	Net             net.IPNet
	Gateway         net.IP
	PreferredSource net.IP
	IfcIndex        int
}

IPRoute represents a route in the kernel's routing table. Any route with a nil Gateway is a directly connected network.

type Notifier

type Notifier struct {
	sync.Mutex
	// contains filtered or unexported fields
}

Notifier represents a new network change Notifier.

func NewNotifier

func NewNotifier(delay time.Duration) *Notifier

NewNotifier returns a new network change Notifier.

func (*Notifier) GetIPRoutes

func (n *Notifier) GetIPRoutes(defaultOnly bool) []route.IPRoute

GetIPRoutes implements netconfig.Notifier. nolint: gocyclo

func (*Notifier) NotifyChange

func (n *Notifier) NotifyChange() (<-chan struct{}, error)

NotifyChange implements netconfig.Notifier.

func (*Notifier) Shutdown

func (n *Notifier) Shutdown()

Shutdown implements netconfig.Notifier.
