Can you be specific?
The phrase `/dev/random behaviour' does not appear in the man page I
wrote, but the behaviour of getrandom(..., GRND_RANDOM) and the
behaviour of reads from /dev/random are exactly the same in Linux
since getrandom was introduced, and in the patch I proposed, so I'm
not sure what the issue is.
I tried to emphasize that GRND_RANDOM is provided only for source
compatibility with Linux and should generally be avoided:
`This is provided mainly for source compatibility with Linux; there
is essentially no reason to ever use it.'
`(No examples of GRND_RANDOM because it is not useful.)'
`GRND_RANDOM is a little silly.'
But perhaps I left something in that is still confusing and/or gives
the impression that GRND_RANDOM _should_ be used for some
applications; if so, please let me know where?
It's also entirely possible that I'm so steeped in this that what I
wrote is unclear for anyone who is not so steeped in it. Concrete
suggestions or feedback about places where the prose I wrote remains
confusing are welcome.
