#define - problem

Hi,
for debugging we often use things like:

#ifdef MONITOR
  printf("initialized\n");
#endif

Now we had another idea

#ifdef MONITOR
  #define debug_printf printf
#else
  #define debug_printf //
#endif
debug_printf("inittialized\n");

The intention was to replace the word debug_printf with "//". So in the code we can alway use the debug_printf()-funktion without #ifdefs. But it doesn't work.

Any ideas?

"The intention was to replace the word debug_printf with '//'"

No, that won't work - because the preprocessor strips the comments before it does the macros!
(or something like that)

The trick is to double-up the parentheses - see: http://www.keil.com/forum/docs/thread3796.asp
