| * random_seed: Rewrite the generic clock() based seed codeMichael Niedermayer2014-01-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new code is faster and reuses the previous state in case of multiple calls. The previous code could easily end up in near-infinite loops, if the difference between two clock() calls never was larger than 1. This makes fate-parseutils finish in finite time when run in wine, if CryptGenRandom isn't available (which e.g. isn't available if targeting Windows RT/metro). Patch originally by Michael Niedermayer but with some modifications by Martin Storsjö. Signed-off-by: Martin Storsjö <martin@martin.st>

* random_seed: allow to block on /dev/randomMåns Rullgård2010-07-01
| | | | | | | | | | If both /dev/random and /dev/urandom failed to return data, an uninitialised value might be returned. Since most systems have a non-blocking /dev/urandom or have /dev/random with similar properties, the chance of blocking is minimal, and the alternative of returning non-random data is worse.
