[PATCH 0/4] Document regoff_t (and a few minor patches)

[Alejandro Colomar]

Hi Michael,

Documentation for regoff_t + a few minor patches.
(apply after ptrdiff_t patches)

I removed the reference from ptrdiff_t to regoff_t, as it is not really
relevant to ptrdiff_t.

I see this is fast, so maybe I'll start sending bigger patchsets.
That way it'll be easier for you to apply them sorted.

Cheers,

Alex.

I don;t think this patch is correct. At the least, it needs 
more explanation. As far as I can see, 'timespec' is not just 
about elapsed time. It really is just time, expressed as secs + 
nanosecs. For example, see utimensat(2), which set file timestamps
with nanosec precision.

For the moment, I'm not applying this (and I hope not doing so
doesn't break any following patch).

Thanks,

Michael

I took that wording from timeval.3bsd. But I think you're correct.

That's fine.  It shouldn't break anything.
