You don't need C99 to make printf()'s portable for integer types that
might have different widths on different platforms -- only C89! :-)
... or at least support in the compiler for concatenating adjacent
strings.
C99 does make this easier by requiring standard macro definitions for
format specifiers, but you can still define your own:
in some application-specific portability header:
#ifdef OFF_T_IS_LONG_LONG
# define MY_OFF_T_FMT "%lld"
#endif
#ifdef OFF_T_IS_LONG
# define MY_OFF_T_FMT "%ld"
#endif
and then in the code:
printf("off_t value is: " MY_OFF_T_FMT ".\n", (off_t) foo);
(BTW, ``Just say NO to operating systems with "LARGE FILE SUPPORT"!!!!''
What a stupid idea that was just to appease the bass-ackwards ABI
nutcases.)
