u32 prandom32

(

struct rnd_state *

state

)

prandom32 - seeded pseudo-random number generator. : pointer to state structure holding seeded state.

This is used for pseudo-randomness with no outside seeding. For more random results, use random32().

random32 - pseudo random number generator

A 32 bit pseudo-random number is generated using a fast algorithm suitable for simulation. This algorithm is NOT considered safe for cryptographic use.
