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

Use this macro to enable or disable the printf.

//Uncomment the following line to enable the printf function.
//#define ENABLE_PRINTF
#ifdef ENABLE_PRINTF
    #define    DEBUG_PRINTF(f,...)    printf(f,##__VA_ARGS__)
#else
    #define    DEBUG_PRINTF(f,...)
#endif

Then call "DEBUG_PRINTF" instead of "printf".

For example:

DEBUG_PRINTF("Hello world: %d", whateverCount);
