Description [src] 

interface Hinoko.FwIsoResource : GObject.Object

A set of basic interfaces to listen to events about isochronous resource. HinokoFwIsoResource includes interfaces to listen to events about allocation and deallocation of isochronous resource.

Available since: 0.7

Prerequisite

In order to implement FwIsoResource, your type must inherit fromGObject.

Implementations

Functions

hinoko_fw_iso_resource_calculate_bandwidth

Calculate the amount of bandwidth expected to be consumed in allocation unit by given parameters.

Instance methods

hinoko_fw_iso_resource_allocate

Initiate allocation of isochronous resource without any wait. One of the candidates is actually allocated for channel. When the allocation finishes, HinokoFwIsoResource::allocated signal is emitted to notify the result, channel, and bandwidth.

since: 1.0

hinoko_fw_iso_resource_allocate_wait

Initiate allocation of isochronous resource and wait for HinokoFwIsoResource::allocated signal. One of the candidates is actually allocated for channel.

since: 1.0

hinoko_fw_iso_resource_create_source

Create GSource for GMainContext to dispatch events for isochronous resource.

since: 0.7

hinoko_fw_iso_resource_open

Open Linux FireWire character device to delegate any request for isochronous resource management to Linux FireWire subsystem.

since: 0.7

Signals

Hinoko.FwIsoResource::allocated

Emitted when allocation of isochronous resource finishes.

since: 0.7

Hinoko.FwIsoResource::deallocated

Emitted when deallocation of isochronous resource finishes.
