Class
HinokoFwIsoIrMultiple
Description [src]
class Hinoko.FwIsoIrMultiple : GObject.Object {
parent_instance: GObject
}An object to receive isochronous packet for several channels.
HinokoFwIsoIrMultiple receives isochronous packets for several channels by buffer-fill mode of
IR context in 1394 OHCI.
Instance methods
hinoko_fw_iso_ir_multiple_allocate
Allocate an IR context to 1394 OHCI hardware for buffer-fill mode. A local node of the node corresponding to the given path is used as the hardware, thus any path is accepted as long as process has enough permission for the path.
hinoko_fw_iso_ir_multiple_get_payload
Retrieve data for packet indicated by the index parameter. The data has isochronous packet header in its first quadlet, timestamp in its last quadlet. The rest is data of isochronous packet.
since: 0.7
hinoko_fw_iso_ir_multiple_map_buffer
Map an intermediate buffer to share payload of IR context with 1394 OHCI hardware.
Methods inherited from HinokoFwIsoCtx (6)
hinoko_fw_iso_ctx_create_source
Create GSource for GMainContext to dispatch events for isochronous context.
since: 0.7
hinoko_fw_iso_ctx_flush_completions
Flush isochronous context until recent isochronous cycle. The call of function forces the context to queue any type of interrupt event for the recent isochronous cycle. Application can process the content of isochronous packet without waiting for actual hardware interrupt.
since: 0.7
hinoko_fw_iso_ctx_read_cycle_time
Retrieve the value of cycle time register. This method call is available once any isochronous context is created.
since: 1.0.
hinoko_fw_iso_ctx_release
Release the contest from 1394 OHCI hardware.
since: 0.7
hinoko_fw_iso_ctx_stop
Stop isochronous context.
since: 0.7
hinoko_fw_iso_ctx_unmap_buffer
Unmap intermediate buffer shared with 1394 OHCI hardware for the context.
since: 0.7
Properties
Hinoko.FwIsoIrMultiple:channels
The array with elements to express isochronous channels to be listened to.
Properties inherited from HinokoFwIsoCtx (2)
HinokoFwIsoCtx:bytes-per-chunk
The number of bytes per chunk in buffer.
since: 0.7
HinokoFwIsoCtx:chunks-per-buffer
The number of chunks per buffer.
since: 0.7
Signals
Hinoko.FwIsoIrMultiple::interrupted
Emitted when Linux FireWire subsystem generates interrupt event. There are two cases for Linux FireWire subsystem to generate the event:
Signals inherited from GObject (1)
GObject::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.
