Hi David.

How about to use getrandom instead of random?

Best regards

Hi aleks. Getrandom is available since 3.17 kernel version (I think correct
me if I m wrong) as a syscall. Plus good care needs for its call in non
blocking mode I think. Cheers.

Plus not sure it really fits the usage here after second thoughts. Regards.

As far as I have your patch understood it looks to me that a new random value should be returned.

As I'm not an expert I just want to ask if this new feature makes here sense.

I have seen this flag GRND_NONBLOCK have anyone experience with this function in no blocking application?

Best regards
Aleks
