#define macro for debug printing in C?

Question

Trying to create a macro which can be used for print debug messages when DEBUG is defined, like the following pseudo code:

#define DEBUG 1
#define debug_prin         


        

Answer 1

This is what I use:

#if DBG
#include 
#define DBGPRINT printf
#else
#define DBGPRINT(...) /**/  
#endif

It has the nice benefit to handle printf properly, even without additional arguments. In case DBG ==0, even the dumbest compiler gets nothing to chew upon, so no code is generated.
