<heavy sarcasm> Oh, please, that _can't_ be right (and it sure looks
ugly too!). Magic strings to generate a printf() specifier for print a
fixed-width integer? </heavy sarcasm>
C99 has definitely gone completely to the dogs.
Meanwhile casting to an explicit basic integer type that's sure to be at
least as wide as the value to be formatted and then just using the
proper explicit format specifier for that basic integer type will also
obviously work too, just as good C programmers have been doing for time
printf("%llu", (unsigned long long) var_u64);
And of course there's still always the option of using an explicit
function, or just a simple little mod loop, to convert an integer to a
string and then just print the string. :-)
