◆ RandomSeed32()

std::mt19937::result_type RandomSeed32 ( )

A 32-bit random value suitable for seeding a 32-bit random number generator. Computing this value may require blocking device I/O but does not require waiting to accumulate entropy. Thus, this function:

  • may be called at runtime (e.g., the first time a given r.n.g. is needed)
  • should not be called frequently (e.g., once per transaction is too often)
  • should not be used as a source of randomness (use a r.n.g. instead)
