HinokoFwIsoIrSingle::interrupted

since: 1.0

Declaration 

void
interrupted (
  HinokoFwIsoIrSingle* self,
  guint sec,
  guint cycle,
  gpointer header,
  guint header_length,
  guint count,
  gpointer user_data
)

Description [src]

Emitted when Linux FireWire subsystem generates interrupt event. There are three cases for Linux FireWire subsystem to generate the event:

  • When 1394 OHCI hardware generates hardware interrupt as a result to process the isochronous packet for the buffer chunk marked to generate hardware interrupt.
  • When the size of accumulated context header for packets since the last event reaches the size of memory page (usually 4,096 bytes).
  • When application calls hinoko_fw_iso_ctx_flush_completions() explicitly.

The handler of signal can retrieve context payload of received packet by call of hinoko_fw_iso_ir_single_get_payload().

Default handler:

The default handler is called after the handlers added via g_signal_connect().

Available since: 1.0

Parameters

sec

Type: guint

Sec part of isochronous cycle when interrupt occurs, up to 7.

cycle

Type: guint

Cycle part of of isochronous cycle when interrupt occurs, up to 7999.

header

Type: An array of guint8

The headers of IR context for packets handled in the event of interrupt. The content is different depending on header_size parameter of hinoko_fw_iso_ir_single_allocate().

The length of the array is specified in the header_length argument.
header_length

Type: guint

The number of bytes for header.

count

Type: guint

The number of packets to handle.
