ConfigureDatagramSocketBuffers sets socket buffers sized for mtu.

func HostConn(hostFD int) (*os.File, net.Conn, error)

HostConn wraps hostFD as a net.Conn. The returned file is retained so callers can close both the connection and file explicitly.

func NewAttachment(guestFD int, mtu int) (foundation.NSFileHandle, vz.VZFileHandleNetworkDeviceAttachment, error)

NewAttachment creates a VZ file-handle network attachment from guestFD.

func NewDevice(attachment vz.VZFileHandleNetworkDeviceAttachment) (vz.VZVirtioNetworkDeviceConfiguration, error)

NewDevice creates a Virtio network device for attachment.

func NewFileHandleFromFD(fd int) foundation.NSFileHandle

NewFileHandleFromFD wraps fd in an NSFileHandle that closes on dealloc.

type Pair struct {
	HostFD  int
	GuestFD int
}

Pair is a connected datagram socket pair for a VZ file-handle network device.

func NewSocketPair(mtu int) (Pair, error)

NewSocketPair returns a connected AF_UNIX datagram socket pair.

func (p Pair) Close()

Close closes both descriptors in p.
