The implementation happened across multiple glibc commits, but the work
was completed for glibc 2.33.

Thanks for the patch!

May I ask that you CC me in patches?  I sometimes miss patches sent only to the 
list.  (If there are any other patches from you that I ignored, please ping).

See a minor formatting comment below.

BTW, I remember some month ago having followed the discussion about adding 
arc4random(3).  Did you finally add it?  If so, would any of you (glibc 
programmers) mind sending a manual page?

Thanks a lot!

Cheers,

Alex

Would you please reformat to use semantic line breaks?

man-pages(7):
    Use semantic newlines
        In  the  source of a manual page, new sentences should be
        started on new lines, long sentences should be split into
        lines at clause breaks (commas, semicolons,  colons,  and
        so on), and long clauses should be split at phrase bound‐
        aries.   This  convention,  sometimes  known as "semantic
        newlines", makes it easier to see the effect of  patches,
        which often operate at the level of individual sentences,
        clauses, or phrases.

I'll try to remember that.

It's in glibc 2.36.  I don't have a manual page yet.

Thanks,
Florian
