prototype of fprintf function in ccs
PostPosted: Thu Dec 27, 2012 4:09 am     Reply with quote
I'm trying to get fprintf function working only when DEBUG is defined. This worked ok for printf, but it seems I can't get the right prototype for fprintf function.

Code:
#ifdef DEBUG
   #define debug_printf fprintf
#else
   #define debug_printf fprintf_dummy
#endif

void fprintf_dummy(char *string, char *format, ...){

}   


I get compiler error: "Attempt to create a pointer to a constant"

Is there any better way to do it? I would like to have debug_printf function that I can use as a standard printf. For example:
Code:
void debug_printf(char *format, ...){
#IFDEF DEBUG
  fprintf(RS232_DEBUG, ........); // I'm not sure how to pass all parameters to fprintf function
#ENDIF
}

Thank you Mike for the link. For now, gribas proposed best solution with #define trace... I was hoping for a little bit more elegant solution, but this will do.
