There are no guarantees, but most likely, yes, they are the same. To find
out search through your code where uint32_t and uint_32 are defined and make
sure they are the same. For all likelyhood they will be the same. It's a
good idea to check though.

Well, is it your code on the other end of the network also? If it's your
code then it will be what you set it to. If it's not your code, you'll need
to check the documentation to see what they expect the size of their ints to
be.

But, yes, uint_xxx_t should be the the same size on each architecture. I'm
not positive it's declared in the standard, however, I don't have a copy of
the standard handy.
