print to console or /dev/null for debugging info

[jeanluca]

Hi All

I need a solution for my debug functionallity. Depending on the variable DEBUG, messages should or shouldn't appear in the console.

Can this be done with fprintf ? If DEBUG is 0 it should point to /dev/null and if 1 to the console (if it exists) ?

Any suggestions ?

thnx in advance
Luca

#ifdef DEBUG
#define fdebug stdout
#else
#define fdebug stderr
#endif

...

fprintf( fdebug, ... );

Something like that?

Or perhaps something like this?

FILE* debug;

if (DEBUG)
   debug = fopen("/dev/null", "w");
else
   debug = stderr; /* or stdout */

fprintf(debug, "Debug Information");
