Types

type Device

type Device interface {
	File() *os.File                 // returns the file descriptor of the device
	Read([]byte, int) (int, error)  // read a packet from the device (without any additional headers)
	Write([]byte, int) (int, error) // writes a packet to the device (without any additional headers)
	Flush() error                   // flush all previous writes to the device
	Name() (string, error)          // fetches and returns the current name
	Close() error                   // stops the device and closes the event channel
}

func CreateTUN

func CreateTUN(ifname string, mtu int) (Device, error)

CreateTUN creates a Wintun interface with the given name. Should a Wintun interface with the same name exist, it is reused.

func CreateTUNWithRequestedGUID

func CreateTUNWithRequestedGUID(ifname string, requestedGUID *windows.GUID, mtu int) (Device, error)

CreateTUNWithRequestedGUID creates a Wintun interface with the given name and a requested GUID. Should a Wintun interface with the same name exist, it is reused.
