Attributes: qualified_only InOut: Scope Name Type Initial Comment Constant gcdwCOBIDMask DWORD 16#1FFFFFFF Bit Mask for calculating the CANID. Example: dwCOBID := pMsg^.cobId AND MASKS.gcdwCOBIDMask gcdwTXMask DWORD 16#80000000 Bit Mask for calculating the Tx bit. Example: xTxMsg := (pMsg^.cobId AND MASKS.gcdwTXMask) > 0 gcdwRTRMask DWORD 16#40000000 Bit Mask for calculating the RTR bit. Example: xRTRMsg := (pMsg^.cobId AND MASKS.gcdwRTRMask) > 0 gcdwEIDMask DWORD 16#20000000 Bit Mask for calculating the EID (= Extended Identifer; 29 bit) bit.

Structures ¶ ARRAY_RECV_ENTRY (Struct) MESSAGE (Struct)
ARRAY_RECV_ENTRY (STRUCT) ¶ TYPE ARRAY_RECV_ENTRY : STRUCT This stucture defines a COBID entry for an Array Receiver created by CL2._CreateArrayReceiver . InOut: Name Type Comment dwCOBID COBID COBID of the array receiver entry. hHandle CAA.HANDLE Last receive message handle for the given COBID.
MESSAGE (STRUCT) ¶ TYPE MESSAGE : STRUCT This structure defines a CANL2 message. Only use this structure if you are using unmanaged CANL2 functions (functions with underscore). For unmanaged CL2 functions the returned handle hMsg can be interpreted as a pointer to this structure because no resource manager is involved. For interpreting the structure members use the bit masks defined in MASKS . InOut: Name Type Comment cobId COBID Contains CANID and Tx/RTR/Extended Identifier bit. Use appropriate bit masks defined in MASKS for calculating the correct value. abyData DATA Data array of CAN message. dwTSP DWORD Receive message: Rx timestamp (set by driver, if supported); Transmit message: time to live. After this time the message will be discarded by the driver (if supported). byLen BYTE Contains DLC. Use bit mask MASKS.gcbyDLCMask for calculating the message length. byNet BYTE CAN Network ID this messages belongs to (do not change!).
