Well, no, I don't personally think that it will fail and certainly even if a read call to /dev/random fails, the whole function will not fail. As I said, I was trying to emulate the glibc getentropy and all its semantics. > From what I recall, it was Bruce that suggested rdseed should be > included as one of the sources.

In light of new attacks on rdseed, it should probably just be removed, IMHO. https://www.phoronix.com/scan.php?page=article&item=crosstalk-srbds-vulnerability&num=1 thanks d
