Class
HinawaFwFcp
Description [src]
class Hinawa.FwFcp : Hinawa.FwResp {
parent_instance: HinawaFwResp
}A FCP transaction executor to node in IEEE 1394 bus.
HinawaFwFcp supports Function Control Protocol (FCP) in IEC 61883-1. FCP transaction consists
of a pair of asynchronous transactions for command and response, while the protocol has no
mechanism to match them. In AV/C Digital Interface Command Set General Specification Version 4.2
(Sep 1 2004, 1394TA), they are loosely matched by the content of their frames, and this class
employs the way.
Any of transaction frames should be aligned to 8 bit (1 byte). This class is an application of
HinawaFwReq / HinawaFwResp.
Instance methods
hinawa_fw_fcp_avc_transaction
Finish the pair of asynchronous transaction for AV/C command and response. The timeout_ms
parameter is used to wait for response transaction since the command transaction is initiated.
The timeout is not expanded in the case that AV/C INTERIM status arrived, thus the caller should
expand the timeout in advance for the case.
since: 4.0
hinawa_fw_fcp_avc_transaction_with_tstamp
Finish the pair of asynchronous transaction for AV/C command and response. The timeout_ms
parameter is used to wait for response transaction since the command transaction is initiated.
The timeout is not expanded in the case that AV/C INTERIM status arrived, thus the caller should
expand the timeout in advance for the case.
since: 2.6
hinawa_fw_fcp_command
Transfer command frame for FCP. When receiving response frame for FCP, HinawaFwFcp::responded
signal is emitted.
since: 4.0
hinawa_fw_fcp_command_with_tstamp
Transfer command frame for FCP. When receiving response frame for FCP, HinawaFwFcp::responded
signal is emitted.
since: 2.6
hinawa_fw_fcp_unbind
Stop to listen to FCP responses. Any pending transactions are forced to be aborted.
since: 1.4
Methods inherited from HinawaFwResp (4)
hinawa_fw_resp_release
Stop listening to the address range in Linux system for local nodes.
since: 1.4
hinawa_fw_resp_reserve
Allocate an address range within Linux system for local nodes, each of which expresses 1394
OHCI hardware. Once successful, HinawaFwResp::requested signal will be emitted whenever any
request subactions arrive at the 1394 OHCI hardware within the dedicated range.
since: 4.0
hinawa_fw_resp_reserve_within_region
Allocate an address range within Linux system for local nodes, each of which expresses 1394
OHCI hardware. Once successful, HinawaFwResp::requested signal will be emitted whenever any
request subactions arrive at the 1394 OHCI hardware within the dedicated range.
since: 4.0
hinawa_fw_resp_set_resp_frame
Register byte frame for the response subaction of transaction.
since: 2.0
Properties
Properties inherited from HinawaFwResp (3)
Hinawa.FwResp:is-reserved
Whether a range of address is reserved or not.
since: 2.0
Hinawa.FwResp:offset
The start offset of reserved address range.
since: 2.3
Hinawa.FwResp:width
The width of reserved address range.
since: 2.3
Signals
Hinawa.FwFcp::responded
Emitted when the node transfers asynchronous packet as response for FCP and the process successfully read the content of packet.
since: 4.0
Signals inherited from HinawaFwResp (1)
HinawaFwResp::requested
Emitted when any node transfers request subaction to local nodes within the address range reserved in Linux system.
since: 4.0
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.
