Functions

func NsCreate

func NsCreate() (netns.NsHandle, error)

NsCreate returns a handle to a new network namespace. NsEnter must be used to safely enter and exit the new namespace.

func NsEnter

func NsEnter(ns netns.NsHandle) (func() error, error)

NsEnter locks the current goroutine the OS thread and switches to a new network namespace. The returned function must be called in order to restore the previous state and unlock the thread.
