Macro to turn off printf statements

Question

What MACRO can be used to switch off printf statements, rather than removing them all for deployment builds, I just want to switch them off, skip them, ignore them.

Answer 1

Another possibility would be something like freopen("/dev/null", "w", stdout);

This doesn't exactly disable printf though -- it's roughly equivalent to running your program with stdout redirected to /dev/null, like: ./myprog > /dev/null at the shell prompt.
