| Platform SDK: DLC/NetBIOS |
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.

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.
| Command | Parameter table |
|---|---|
| LLC_DIR_SET_FUNCTIONAL_ADDRESS | usParameter0 and usParameter1 contain the address to be set or reset. |
| LLC_DIR_SET_GROUP_ADDRESS | usParameter0 contains the group address to be set. |
| LLC_DIR_TIMER_CANCEL | usParameter0 and usParameter1 contain the address of the timer to be canceled. |
| LLC_DIR_TIMER_CANCEL_GROUP | usParameter0 and usParameter1 contain the timer completion flag. |
| LLC_DIR_TIMER_SET | usParameter0 contains the timer value. |
| LLC_DLC_CLOSE_SAP | usStationId contains the station identifier of the SAP to be closed and usParameter receives the station identifier of any link station on the SAP that is not closed. |
| LLC_DLC_CLOSE_STATION | usStationId contains the station identifier of the station to be closed. |
| LLC_DLC_FLOW_CONTROL | usStationId contains the station identifier and usParameter specifies one of the following options:
LLC_RESET_LOCAL_BUSY_USER |
| LLC_DLC_RESET | usStationId contains the station identifier of the station to be reset. A value of zero defines all SAPs and all link stations. A value of 0xnn00 defines SAP nn and all its link stations. |
| LLC_READ_CANCEL | ulParameter contains the address of the command control block of the read command to be canceled. |
| LLC_RECEIVE_CANCEL | usStationId contains the station identifier of the SAP or link station of a pending LLC_RECEIVE command that is to be canceled. |
| LLC_RECEIVE_MODIFY | usStationId contains the station identifier and usParameter specifies the length of the user data in the buffers. |
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.
