SNIP_CLASSIC_DLT_SECTION_7_1_9_3_Select_target_LogChannel

7.1.9.3 Select target LogChannel In this step, the Dlt module identifies on which LogChannel(s) the log or trace message will be transmitted. [SWS_Dlt_00664] ⌈For LogChannel selection the Dlt module manages LogChannel to DltSwcApplicationId/DltSwcContextId tuple mappings. (see configuration parameter DltLogChannelAssignmentSwcContextRef).⌋ Note: There can be several LogChannels configured for a given DltSwcApplicationId/DltSwcContextId tuple contained in a Dlt_SendLogMessage or Dlt_SendTraceMessage call. [SWS_Dlt_00665] ⌈To find the matching LogChannels for the DltSwcApplicationId/DltSwcContextId tuple contained in a Dlt_SendLogMessage or Dlt_SendTraceMessage call, the Dlt module shall do the following steps: • From all mapping elements, where DltSwcApplicationId/DltSwcContextId tuple of mapping element equals to the DltSwcApplicationId/DltSwcContextId tuple of the log/trace message, the LogChannel shall be added to the list of output LogChannels. • From all mapping elements, where ApplicationID of mapping element equals to the ApplicationID of the log/trace message AND the ContextId of mapping element equals wildcard (value 0x00000000), the LogChannel shall be added to the list of output LogChannels. • If the list of output LogChannels is still empty after step 1 and 2. The default Log Channel (see configuration parameter DltDefaultLogChannelRef) shall be added to the list of output LogChannels. ⌋
