Class
HitakiSndEfw
Description [src]
class Hitaki.SndEfw : GObject.Object {
parent_instance: GObject
}A GObject-derived object for sound unit of Echo Audio Fireworks.
The HitakiSndEfw is an object class derived from GObject with protocol
implementation for Echo Audio Fireworks devices supported by ALSA fireworks driver
(snd-fireworks).
Constructors
hitaki_snd_efw_new
Instantiate HitakiSndEfw object and return it.
Instance methods
Methods inherited from HitakiAlsaFirewire (4)
hitaki_alsa_firewire_create_source
Allocate GSource to handle events from ALSA HwDep character device.
hitaki_alsa_firewire_lock
Lock kernel driver bound to the associated ALSA HwDep character device so that it is prohibited to start packet streaming.
hitaki_alsa_firewire_open
Open the special file for ALSA HwDep character device.
hitaki_alsa_firewire_unlock
Unlock kernel driver bound to the associated ALSA HwDep character device so that it can start packet streaming.
Methods inherited from HitakiEfwProtocol (3)
hitaki_efw_protocol_receive_response
Parse the given buffer for response frame of Fireworks transaction. The buffer should includes
one response frames at least. It results in HitakiEfwProtocol::responded per response frame.
It’s expected that the function is used by any implementation of HitakiEfwProtocol.
hitaki_efw_protocol_transaction
Transfer asynchronous transaction for request frame of Echo Efw protocol and wait for response
matched to the command. The call results in HitakiEfwProtocol::responded signal with data of response.
hitaki_efw_protocol_transmit_request
Transfer asynchronous transaction for request frame of Fireworks transaction. It calls
Hitaki.EfwProtocolInterface.transmit_request internally after composing request frame. It results in
HitakiEfwProtocol::responded signal with response parameters when receiving response for the transaction.
Properties
Properties inherited from HitakiAlsaFirewire (6)
Hitaki.AlsaFirewire:card-id
The numeric identifier for sound card.
Hitaki.AlsaFirewire:guid
Global unique identifier for the node in IEEE 1394 bus.
Hitaki.AlsaFirewire:is-disconnected
Whether the sound card is unavailable. It becomes FALSE when the sound card is removed or
driver is unbound to it. Then the owner of this object should call
g_object_unref() as quickly as possible to release ALSA hwdep character device.
Hitaki.AlsaFirewire:is-locked
Whether the associated unit is locked or not to start packet streaming.
Hitaki.AlsaFirewire:node-device
The name of node device in Linux FireWire subsystem which owns the unit; e.g. fw1.
Hitaki.AlsaFirewire:unit-type
The type of sound unit.
Signals
Signals inherited from GObject (1)
GObject.Object::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
Signals inherited from HitakiEfwProtocol (1)
Hitaki.EfwProtocol::responded
Emitted when the unit transfers asynchronous packet as response of Echo Audio Efw transaction and the process successfully reads the content of response from ALSA Efw driver.
