Ok, so this is what I have now:
#define USER_EVENTS_LOGGING          0x00000001
#define COMMUNICATOIN_BUS_LOGGING    0x00000002
uint32_t enabledMyGrpBitFlags = 0;

#if defined(ENABLE_USER_EVENTS_LOGGING)
#define TRACE_EX(grp, myGrp, lvl, ...)   if (myGrp & USER_EVENTS_LOGGING)       printf_(__VA_ARGS__)
#elif defined(ENABLE_COMMUNICATOIN_BUS_LOGGING)
#define TRACE_EX(grp, myGrp, lvl, ...)   if (myGrp & COMMUNICATOIN_BUS_LOGGING) printf_(__VA_ARGS__)
#else
#define TRACE_EX(grp, myGrp, lvl, ...)                                                 \
	do {                                                                               \
		if (myGrp & enabledMyGrpBitFlags) {                                            \
			printf_(__VA_ARGS__);                                                      \
		}                                                                              \
		traceToPrintStream(grp, __FILE__, __FUNCTION__, __LINE__, lvl, __VA_ARGS__);   \
    } while (0)
#endif
Is it possible to remove the run-time checks:
if (myGrp & USER_EVENTS_LOGGING) 
if (myGrp & COMMUNICATOIN_BUS_LOGGING)
so that the TRACE_EX macro would become empty when the myGrop isn't matching? In other words, let's say only ENABLE_USER_EVENTS_LOGGING (not ENABLE_COMMUNICATOIN_BUS_LOGGING) is defined, then I would like the following line to "disappear" after the preprocessor is finished:
TRACE_EX("regCallbacks", COMMUNICATION_BUS, T_D, "Write to reg %d. First written byte: 0x%X", regAddr, regValues[0]);
Is that possible somehow?
