— When writing C is better to use uint or uint_t ?

— Int is signed and uint is unsigned

— No mean the t sorry

— Uint vs uint_t

— 

But if u meant should i use Exact-width integer types then use they can be nice for portability in other machines

— Ok thanks

— Yes please

— Be aware that int32_t is optional and not available on every architecture while int is mandatory.

— 👍

— Optional kind of implies it's a GCC extension or something

— It's available everywhere that conforms to C99+ or C11+

— No, but you can't guarantee availability because there are systems where a byte is not 8 bits and hence you can't have that type

— But that's exactly why these things were implemented

— The only case in which they don't exist is e.g uint64_t in an architecture that only holds up to 32 bits
