Detailed Description

standard way to get a random seed: unsigned int seed = PHRandomSeed(); It return fix seed sequence if recoConsts RANDOMSEED is set. If values are preloaded via PHRandomSeed::LoadSeed, they are returned in loaded order otherwise it return a random seed from std::random_device rdev
