class Device

Defined at line 4593 of file fidling/gen/sdk/fidl/fuchsia.net.tun/fuchsia.net.tun/hlcpp/fuchsia/net/tun/cpp/fidl.h

Provides control over the created device.

This protocol encodes the underlying object's lifetime in both directions;

the underlying object is alive iff both ends of the protocol are open. That

is:

- Closing the client end causes the object to be destroyed.

- Observing a closure of the server end indicates the object no longer

exists.

Public Methods

void ~Device ()
void WriteFrame (::fuchsia::net::tun::Frame frame, WriteFrameCallback callback)

Writes a frame to the device (data coming from network-end).

If the device was created with the

[`fuchsia.net.tun/DeviceConfig.blocking`] option set to `true`, calls to

`WriteFrame` block until there is one buffer available to fulfill the

request.

+ request `frame` inbound frame data and metadata.

* error `ZX_ERR_NOT_FOUND` if [`Frame.port`] references an unknown port.

* error `ZX_ERR_INVALID_ARGS` if `frame` is invalid.

* error `ZX_ERR_BAD_STATE` if the device is offline.

* error `ZX_ERR_NO_RESOURCES` if more than

[`fuchsia.net.tun/MAX_PENDING_OPERATIONS`] calls to `WriteFrame` are

pending.

* error `ZX_ERR_SHOULD_WAIT` if `blocking` is set to `false` and there

are no buffers available to fulfill the request.

void ReadFrame (ReadFrameCallback callback)

Gets the next frame from the device (data coming from host-end).

If the device was created with the

[`fuchsia.net.tun/DeviceConfig.blocking`] option set to `true`, calls to

`ReadFrame` block until there is a frame available to be read.

- response `frame` outbound frame data and metadata.

* error `ZX_ERR_NO_RESOURCES` if more than

[`fuchsia.net.tun/MAX_PENDING_OPERATIONS`] calls to `ReadFrame` are

pending.

* error `ZX_ERR_SHOULD_WAIT` if `blocking` is set to `false` and there

are no frames to be read.

void GetSignals (GetSignalsCallback callback)

Retrieves signals eventpair.

- response `signals` an eventpair that is signalled with

`SIGNAL_READABLE` and `SIGNAL_WRITABLE` when read and write buffers are

available, respectively.

void AddPort (::fuchsia::net::tun::DevicePortConfig config, ::fidl::InterfaceRequest< ::fuchsia::net::tun::Port> port)

Creates a new port on this device.

+ request `config` new port configuration.

+ request `port` grants control over the port. Closed with an epitaph if

`config` is not valid.

void GetDevice (::fidl::InterfaceRequest< ::fuchsia::hardware::network::Device> device)

Connects to the underlying device endpoint.

+ request `device` device handle.

void DelegateRxLease (::fuchsia::hardware::network::DelegatedRxLease lease)

Delegates an rx lease through the tun device.

See documentation on [`fuchsia.hardware.network/DelegatedRxLease`] for

proper usage.
