Class
HinawaFwFcp
Description [src]
class Hinawa.FwFcp : Hinawa.FwResp {
parent_instance: HinawaFwResp
}A FCP transaction executor to node in IEEE 1394 bus. A HinawaFwFcp supports Function Control Protocol (FCP) in IEC 61883-1, in which no way is defined to match response against command by the contents of frames. In ‘AV/C Digital Interface Command Set General Specification Version 4.2’ (Sep 1 2004, 1394TA), a pair of command and response is loosely matched by the contents of frames.
Any of transaction frames should be aligned to 8bit (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 transactions. The
timeout_ms parameter is used to wait for response transaction since the command transaction is
initiated, ignoring HinawaFwFcp:timeout property of instance. The timeout is not expanded in
the case that AV/C INTERIM status is arrived, thus the caller should expand the timeout in
advance for the case.
since: 2.1.
hinawa_fw_fcp_command
Transfer command frame for FCP. When receiving response frame for FCP, HinawaFwFcp::responded
signal is emitted.
since: 2.1.
hinawa_fw_fcp_transaction
Finish the pair of command and response transactions for FCP. The value of
HinawaFwFcp:timeout property is used to wait for response transaction since the command
transaction is initiated.
deprecated: 2.1 since: 1.4.
Methods inherited from HinawaFwResp (5)
hinawa_fw_resp_get_req_frame
Retrieve byte frame to be requested.
deprecated: 2.2 since: 2.0
hinawa_fw_resp_release
Stop to listen to a range of address in local node (e.g. OHCI 1394 controller).
since: 1.4.
hinawa_fw_resp_reserve
Start to listen to a range of address in host controller which connects to the node. The function
is a variant of hinawa_fw_resp_reserve_within_region() so that the exact range of address should
be reserved as given.
since: 1.4.
hinawa_fw_resp_reserve_within_region
Start to listen to range of address equals to #width in local node (e.g. 1394 OHCI host controller), which is used to communicate to the node given as parameter. The range of address is looked up in region between region_start and region_end.
since: 2.3.
hinawa_fw_resp_set_resp_frame
Register byte frame as response.
since: 2.0
Properties
Properties inherited from HinawaFwResp (3)
Hinawa.FwResp:is-reserved
Whether a range of address is reserved or not in host controller.
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: 2.1
Signals inherited from HinawaFwResp (2)
HinawaFwResp::requested
Emitted when any node transfers requests to the range of address to which this object
listening, the HinawaFwResp::requested signal handler is called with HinawaFwTcode,
without the case that HinawaFwResp::requested2 signal handler is already assigned.
deprecated: 2.2 since: 0.3
HinawaFwResp::requested2
Emitted when any node transfers request subaction to the range of address to which this
object listening, the HinawaFwResp::requested signal handler is called with arrived
frame for the subaction. The handler is expected to call hinawa_fw_resp_set_resp_frame()
with frame and return HinawaFwRcode for response subaction.
since: 2.2
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.
