CCB_PARMS Overview  Group

The CCB_PARMS union represents the DLC parameter table. You can present the parameter table as a pointer to a structure, two USHORT values, an array of four UCHAR values, or a single ULONG value. You pass a pointer to this structure to the AcsLan function, through the u member of the LLC_CCB structure.

pParameterTable

Specifies a pointer to a structure in the LLC_PARMS union that represents the parameter table. The LLC_PARMS union represents all parameter table structures for DLC. The DLC command determines the particular structure to use, as shown in the following table.

Command	Parameter Table
LLC_BUFFER_CREATE	LLC_BUFFER_CREATE_PARMS
LLC_BUFFER_FREE	LLC_BUFFER_FREE_PARMS
LLC_BUFFER_GET	LLC_BUFFER_GET_PARMS
LLC_DIR_INITIALIZE	LLC_DIR_INITIALIZE_PARMS
LLC_DIR_OPEN_ADAPTER	LLC_DIR_OPEN_ADAPTER_PARMS
LLC_DIR_OPEN_DIRECT	LLC_DIR_OPEN_DIRECT_PARMS
LLC_DIR_READ_LOG	LLC_DIR_READ_LOG_PARMS
LLC_DIR_SET_EXCEPTION_FLAGS	LLC_DIR_SET_EFLAG_PARMS
LLC_DIR_SET_MULTICAST_ADDRESS	LLC_DIR_MULTICAST_ADDRESS
LLC_DIR_STATUS	LLC_DIR_STATUS_PARMS
LLC_DLC_CONNECT_STATION	LLC_DLC_CONNECT_PARMS
LLC_DLC_MODIFY	LLC_DLC_MODIFY_PARMS
LLC_DLC_OPEN_SAP	LLC_DLC_OPEN_SAP_PARMS
LLC_DLC_OPEN_STATION	LLC_DLC_OPEN_STATION_PARMS
LLC_DLC_REALLOCATE_STATIONS	LLC_DLC_REALLOCATE_PARMS
LLC_DLC_SET_THRESHOLD	LLC_DLC_SET_THRESHOLD_PARMS
LLC_DLC_STATISTICS	LLC_DLC_STATISTICS_PARMS
LLC_READ	LLC_READ_PARMS
LLC_RECEIVE	LLC_RECEIVE_PARMS
LLC_TRANSMIT_DIR_FRAME	LLC_TRANSMIT_PARMS
LLC_TRANSMIT_I_FRAME	LLC_TRANSMIT_PARMS
LLC_TRANSMIT_TEST_CMD	LLC_TRANSMIT_PARMS
LLC_TRANSMIT_UI_FRAME	LLC_TRANSMIT_PARMS
LLC_TRANSMIT_XID_CMD	LLC_TRANSMIT_PARMS
LLC_TRANSMIT_XID_RESP_FINAL	LLC_TRANSMIT_PARMS
LLC_TRANSMIT_XID_RESP_NOT_FINAL	LLC_TRANSMIT_PARMS

usStationId

Specifies the station identifier.

usParameter

Specifies an optional parameter.

usParameter0

The first optional parameter.

usParameter1

The second optional parameter.

auchBuffer

Specifies a group or functional address.

ulParameter

Specifies the parameter table.

Remarks

The following table shows how the usStationId, usParameter, usParameter0, usParameter1, auchBuffer, and ulParameter members are used by the commands whose parameter tables are not represented by a unique LLC_PARMS structure.

Remarks

If an LLC_READ command is pending that requests notification of data to be received, the cancellation of the LLC_RECEIVE command does not affect the LLC_READ command. After the LLC_RECEIVE_CANCEL command completes, the pNext member of the LLC_CCB structure contains the address of the canceled LLC_RECEIVE command.
