Wortlaut

8.4.6.2 EthIf_GetCurrentTime [SWS_EthIf_00154] Definition of API function EthIf_GetCurrentTime Status: OBSOLETE ⌈ Service Name EthIf_GetCurrentTime (obsolete) Syntax Std_ReturnType EthIf_GetCurrentTime ( uint8 CtrlIdx, Eth_TimeStampQualType* timeQualPtr, Eth_TimeStampType* timeStampPtr ) Service ID [hex] 0x22 Sync/Async Synchronous Reentrancy Non Reentrant Parameters (in) CtrlIdx Index of the addresses ETH controller. Parameters (inout) None timeQualPtr quality of HW time stamp, e.g. based on current drift Parameters (out) timeStampPtr current time stamp Return value Std_ReturnType E_OK: successful E_NOT_OK: failed Description Returns a time value out of the HW registers according to the capability of the HW. Is the HW resolution is lower than the Eth_TimeStampType resolution resp. range, the remaining bits will be filled with 0. Important Note: EthIf_GetCurrentTime may be called within an exclusive area. Tags: atp.Status=obsolete Available via EthIf.h ⌋ [SWS_EthIf_00155] Status: OBSOLETE ⌈If development error detection is enabled: the function shall check that the service EthIf_Init was previously called. If the check fails, the function shall raise the development error ETHIF_E_UNINIT.⌋ [SWS_EthIf_00157] Status: OBSOLETE ⌈If development error detection is enabled: the function shall check the parameter timeQualPtr and timeStampPtr for being valid. If the check fails, the function shall raise the development error ETHIF_E_PARAM_POINTER.⌋ [SWS_EthIf_00158] Status: OBSOLETE ⌈The function shall be pre compile time configurable On/Off by the configuration parameter: EthIfGlobalTimeSupport.⌋ [SWS_EthIf_00473] Status: OBSOLETE ⌈The EthIf module shall apply appropriate mechanisms to allow calls of EthIf_GetCurrentTime API from other partitions than its main function, e.g. by providing an EthIf satellite.⌋
