How should I properly use __attribute__ ((format (printf, x, y))) inside a class method in C++?

Question

I\'m trying to define a class method for debug prints that will behave like printf:

inline void debug(const char* fmt, ...) __attribute__ ((form         


        

Answer 1

Since it only works for gcc, it would be good to define it this way to avoid errors on other compilers.

#ifdef __GNUC__
          __attribute__ (( format( printf, 2, 3 ) ))
#endif
