[lwip-devel] Concerning #define SZT_F PRIuMAX

[Ambroz Bizjak]

Hi all,

With regard to commit
http://git.savannah.gnu.org/cgit/lwip.git/patch/?id=e6bc591a1e194e7b140e039190bd0468314a261b

I'm sure this is wrong generally and specifically on the many (most?)
32-bit platforms, where size_t is 32-bit but uintmax_t is uint64_t.

As far as I know, the C99 standard has %zu for printing a size_t, but
I know this is a problem to use because you cannot know easily if it
is supported.

However, I think that "#define SZT_F PRIuPTR" has a much better chance
of being right, making the assumption that uintptr_t is the same as
size_t.

Best regards,
Ambroz
