The GET_LOCAL_HOST_INFO1 structure contains the data returned by a REQUEST_GET_LOCAL_HOST_INFO request using u.GetLocalHostInformation.nLevel GET_HOST_UNIQUE_ID. This structure is used for a send response. The structure is used in a request yjsy retrieves the next FCP response from the queue of requests maintained by the IEC-61883 protocol driver. This structure is used for a send request. This structure is used for a get request. The FCP_FRAME structure describes a function control protocol (FCP) request. The CYCLE_TIME structure contains the IEEE 1394 isochronous cycle time. The CONFIG_ROM structure is used to contain the first 24 bytes of an IEEE 1394 device's configuration ROM. This structure is used to assign settings to a plug. This structure is used by the PCMP_NOTIFY_ROUTINE callback.
The request allows a driver to monitor all access to local oPCR and iPCR plugs. This structure is used to monitor plug access. The CMP_MONITOR_INFO structure is used in conjunction with the Av61883_MonitorPlugs request to allow a driver to monitor access to local oPCR and iPCR plugs. This structure is used in getting the state of a plug. This structure is used in getting the handle of a plug. This structure is used to break a connection. This structure is used to delete a plug.Av61883_CreatePlug. This structure contains information for a connection request. The request attempts to make a connection to a plug control register on the local host. The CIP_VALIDATE_INFO structure contains information about the frame. This structure is used to begin transmission. This structure is used to stop transmission or reception.
The CIP_NOTIFY_INFO structure contains information about the frame. The request begins isochronous reception on the specified connection. This structure is used for a listen request.
The CIP_FRAME structure describes a frame to be attached to an input or output plug. This structure is a CIP data format which is used by CMP_CONNECT_VER2. A frame can be canceled while the stream is running. The request cancels an attached frame buffer. This structure is used in an attach frame request. This structure is used to register or deregister the PBUS_RESET_ROUTINE callback. The BUS_RESET_DATA structure specifies the context for the extended bus reset notification routine. The BUS_GENERATION_NODE structure is used in conjunction with the Av61883_GetUnitInfo request to retrieve bus characteristics. The AV_PCR structure specifies settings for an input or output plug. The AV_61883_REQUEST structure is used to pass requests to the IEC-61883 protocol driver. The ADDRESS_RANGE structure describes a range in a IEEE 1394 device's address space. The ADDRESS_OFFSET structure specifies the 48-bit address within a device's IEEE 1394 address space. The ADDRESS_FIFO structure is an entry in a singly-linked list of MDLs that the REQUEST_ALLOCATE_ADDRESS_RANGE IEEE 1394 bus request uses. This routine is called for plug notification. This routine is called for plug monitoring. This is a caller-supplied function to be called by the protocol driver when the 1394 bus is reset. This enumeration specifies the type of a plug. This enumeration specifies the location of a plug. This enumeration specifies a connection type. The driver has access to all operations provided by the IEEE 1394 bus and its host controller through this request.Īn IEC-61883 client driver uses the IRP_MJ_INTERNAL_DEVICE_CONTROL IRP with IoControlCode IOCTL_61883_CLASS to communicate with 1394 driver stack using the IEC-61883 protocol. IOCTLsĪn IEEE 1394 driver uses the IRP_MJ_INTERNAL_DEVICE_CONTROL IRP, with IoControlCode IOCTL_1394_CLASS, to communicate with the bus driver. To develop IEEE 1394 bus, you need these headers:įor the programming guide, see IEEE 1394 bus.
