Description

A HinawaFwNode is an event listener for a specified node on IEEE 1394 bus. This class is an application of Linux FireWire subsystem. All of operations utilize ioctl(2) with subsystem specific request commands.

Functions

hinawa_fw_node_new ()

HinawaFwNode *
hinawa_fw_node_new (void);

Instantiate HinawaFwNode object and return the instance.

Returns

an instance of HinawaFwNode.

Since: 1.4.

hinawa_fw_node_open ()

void
hinawa_fw_node_open (HinawaFwNode *self,
                     const gchar *path,
                     GError **exception);

Open Linux FireWire character device to operate node on IEEE 1394 bus.

Parameters

self

A HinawaFwNode

  

path

A path to Linux FireWire character device

  

exception

Property Details

The “bus-manager-node-id” property

  “bus-manager-node-id”      gulong

Node-ID for bus manager on the bus at this generation.

Owner: HinawaFwNode

Flags: Read

The “generation” property

  “generation”               gulong

current level of generation on this bus.

Owner: HinawaFwNode

Flags: Read

The “ir-manager-node-id” property

  “ir-manager-node-id”       gulong

Node-ID for isochronous resource manager on the bus at this generation.

Owner: HinawaFwNode

Flags: Read

The “local-node-id” property

  “local-node-id”            gulong

Node-ID for a node which this node use to communicate to the other nodes on the bus at this generation.

Owner: HinawaFwNode

Flags: Read

The “node-id” property

  “node-id”                  gulong

Node-ID of this node at this generation.

Owner: HinawaFwNode

Flags: Read

The “root-node-id” property

  “root-node-id”             gulong

Node-ID for root of bus topology at this generation.

Owner: HinawaFwNode

Flags: Read

Signal Details

The “bus-update” signal

void
user_function (HinawaFwNode *self,
               gpointer      user_data)

When IEEE 1394 bus is updated, the ::bus-update signal is generated. Handlers can read current generation in the bus via 'generation' property.

Parameters

self

A HinawaFwNode.

  

user_data

user data set when the signal handler was connected.

  

Flags: Run Last

Since: 1.4.

The “disconnected” signal

void
user_function (HinawaFwNode *self,
               gpointer      user_data)

When phicical FireWire devices are disconnected from IEEE 1394 bus, the ::disconnected signal is generated.

Parameters

self

A HinawaFwNode.

  

user_data

user data set when the signal handler was connected.

  

Flags: Run Last

Since: 1.4.
