[lwip-devel] [bug #27352] Change ip_addr from struct to typedef (u32_t)

[Simon Goldschmidt]

Follow-up Comment #32, bug #27352 (project lwip):

Ah, for me, aligned was 32-bit since that is the minimum alignment for all
datatypes we have (32-bit maximum) on nearly every platform from 8-bit upt to
x64 (I think there are some DSPs though that need other alignment?).

For 16-bit platforms, you might be right.

I get your idea about the macros now. I have already been thinking about
having preprocessor versions of the htonX functions (that would prevent all
the #if LITTLE_ENDIAN blocks), but I haven't yet checked whether compilers can
optimize shifting of constants away or not.

Until then, I think your idea about the macros is good.
