21 // This is the log macro frontend that funnels everything into the C-based
22 // message hangler facade, i.e. pw_log_string_HandleMessage. It's not efficient
23 // at the callsite, since it passes many arguments.
24 //
25 // Users can configure exactly what is passed to pw_log_string_HandleMessage by
26 // providing their own PW_LOG_STRING_HANDLE_MESSAGE implementation.
