Actually the preferred coding of this is
snprintf(buf, sizeof(buf), ...);
which is both correct and impervious to subsequent alteration of the
declared size of buf. I get antsy whenever I see a snprintf with a
literal-constant size argument, because it's a mistake waiting to
happen. Use sizeof() when you can, or at least a #define.
