macro NAME expansion as string c/C++

Question

I want use the NAME of the macro inside the macro expansion as string.

Example:

#define DEBUG_TEST(a, ...) printf("DEBUG_TEST::%s (%d) : " a, __FUNCTION__, __LINE__, ##__VA_ARGS__)

Want to change to something that doesn't need the "DEBUG_TEST" anymore in the exapansion, but something like:

#define DEBUG_TEST(a, ...) printf(__MACRO__ "::%s (%d) : " a, __FUNCTION__, __LINE__, ##__VA_ARGS__)

Of course in my example __MACRO__ dosen't exist...

Answer 1

I believe this is not possible. My suggestion would be to create another macro that takes the name of the macro as argument. Then use this macro in your other macroses.
