    For those working with older C compilers that don't support variable macro arguments, you can do this:

    #ifdef DEBUG

      #define PRINTD(x) printf

    #else

      #define PRINTD(x) (void(0))

    #endif



    PRINTD(("Hello debugger\n"));

    PRINTD(("The number you dialed, %u, is not in service\n", 911));

    oops that should be
    #define PRINTD(x) printf x

Please comment with your real name using good manners.
