8.3.51 EthIf_Transmit [SWS_EthIf_00075] Definition of API function EthIf_Transmit ⌈ Service Name EthIf_Transmit Syntax Std_ReturnType EthIf_Transmit ( uint8 CtrlIdx, Eth_BufIdxType BufIdx, Eth_FrameType FrameType, boolean TxConfirmation, uint16 LenByte, const uint8* PhysAddrPtr ) Service ID [hex] 0x0a Sync/Async Synchronous Reentrancy Reentrant for different buffer indexes and Ctrl indexes CtrlIdx Index of the Ethernet controller within the context of the Ethernet Interface BufIdx Index of the buffer resource FrameType Ethernet frame type TxConfirmation Activates transmission confirmation LenByte Data length in byte Parameters (in) PhysAddrPtr Physical target address (MAC address) in network byte order Parameters (inout) None Parameters (out) None Return value Std_ReturnType E_OK: success E_NOT_OK: transmission failed Description Triggers transmission of a previously filled transmit buffer Available via EthIf.h ⌋() [SWS_EthIf_00250] ⌈If CtrlIdx refers to an EthIfCtrl where an EthIfVlanID is configured, the parameters FrameType is not used, and 0x8100 is provided to <EthDrv> _Transmit instead.⌋() [SWS_EthIf_00076] ⌈If the latest accepted controller mode is equal to ETH_MODE_ACTIVE or ETH_MODE_ACTIVE_WITH_WAKEUP_REQUEST for the given EthIfController, then the function EthIf_Transmit shall forward the call to the respective Ethernet Controller Driver. Otherwise the function shall reject the request for a transmission and return with E_NOT_OK.⌋() [SWS_EthIf_00077] ⌈If development error detection is enabled: the function shall check that the service EthIf_Init was previously called. If the check fails, the function shall raise the development error ETHIF_E_UNINIT.⌋() [SWS_EthIf_00078] ⌈If development error detection is enabled: the function shall check the parameter CtrlIdx for being valid. If the check fails, the function shall raise the development error ETHIF_E_INV_CTRL_IDX.⌋() [SWS_EthIf_00079] ⌈If development error detection is enabled: the function shall check the parameter BufIdx for being valid. If the check fails, the function shall raise the development error ETHIF_E_INV_PARAM.⌋() [SWS_EthIf_00080] ⌈If development error detection is enabled: the function shall check the parameter PhysAddrPtr for being valid.
