%llu/d is really only correct for values of type 'long long int' however:
e.g. for values of type off_t, PRIdOFF is more correct:
$ gcc -Wall llu.c
llu.c:7:13: warning: format '%lld' expects argument of type 'long long int', but argument 2 has type '__off_t' {aka 'long int'} [-Wformat=]
printf("%lld", ftello(stdin));
e.g. for values of type uint64_t, PRIu64 is more correct:
$ gcc -Wall llu.c
llu.c:7:13: warning: format '%lld' expects argument of type 'long long int',
but argument 2 has type 'long unsigned int' [-Wformat=]
printf("%lld", (uint64_t)ftello(stdin));
But I agree, those inttypes.h printf-formatting macros are not very convenient or easy to remember.
