stdint.h vs. stdio.h

[copx]

How can you use printf/scanf/etc. while using stdint.h types?

I mean if you use int_least64_t for example; how do you know the proper
format identifier?
On a 64bit platform int_least64_t might be defined as "int" (%d) while
on a 32bit platform it might be a "long int" (%ld)..

Using the macros defined in <inttypes.h>

It's extremely ugly, but:
printf("%" PRIdLEAST64 "\n", (int_least64_t) 0);

It's up to the implementation to define the macro as "d", "ld", or
whatever is appropriate for that specific platform.

Don't say anything. Especially you.

You can cast to a known type.
int_ZZ_t zork;
printf("%lld\n",(long long)zork);
