Command returns the shim command with the provided args and configuration

func Connect ¶

func Connect(address string, d func(string, time.Duration) (net.Conn, error)) (net.Conn, error)

Connect to the provided address

func NewSocket ¶

func NewSocket(address string) (net.Listener, error)

NewSocket returns a new npipe listener

func Run ¶

func Run(id string, initFunc Init)

Run initializes and runs a shim server

func SetScore ¶

func SetScore(pid int) error

SetScore sets the oom score for a process

func SocketAddress ¶

func SocketAddress(ctx context.Context, id string) (string, error)

SocketAddress returns a npipe address

func WriteAddress ¶
